The Deposit of Faith
The deposit of faith (depositum fidei) is the body of saving truths and divine revelation, comprising Sacred Scripture and Sacred Tradition, entrusted by Jesus to the Apostles and passed down through the Catholic Church. It is a complete, unchangeable treasure of faith intended to be guarded, interpreted, and shared by the Church.
Sacred Scripture: The written Word of God (the Bible).
Sacred Tradition: The Word of God entrusted to the Apostles by Christ and the Holy Spirit, handed down through oral teaching and the life of the Church. The living transmission of the Word of God, which includes the oral teachings, rituals, and practices handed down from the Apostles.
The Magisterium: The Church's teaching authority (the Pope and bishops) tasked with authentically interpreting and guarding this deposit.
Scriptural Basis: The term is rooted in St. Paul’s letters to Timothy: "O Timothy, guard what has been entrusted to you" (1 Timothy 6:20) and "Guard this rich trust with the help of the holy Spirit" (2 Timothy 1:14).
It contains all that is necessary for the salvation of the world.
The Holy Spirit guides the Church in accurately understanding, interpreting, and preserving these truths through the ages.
It is transmitted and taught by the Church’s Magisterium (teaching authority
While the deposit is "sealed" after the last apostle's death, the Church's understanding of these truths can deepen over time, but the doctrine itself does not change.
The Catechism of the Catholic Church is considered a comprehensive, authoritative collection of these teachings, sometimes referred to by Pope John Paul II in Fidei Depositum as the "compendium of all Catholic doctrine".
The Church is not above the Word of God but serves it by protecting this deposit.
Complete Revelation: Divine revelation is considered "closed" or sealed with the death of the last Apostle (St. John). Nothing can be added to or subtracted from the Deposit of Faith.
While the deposit itself does not change, the Church’s understanding of it can grow and become more explicit over time. For example, terms like "Transubstantiation" were coined centuries later to explain a truth already present in the original deposit.
The question asked of me I have placed here in blue followed by my answer.
I wish to make a point and ask a question.
The point I would make is that I think it is unfair to the discussion to claim the Church has taught this for 2,000 years. Perhaps that was not your intention, but it is certainly not true that the Immaculate Conception has been taught for 2,000 years. Augustine, Bernard and even as late as Aquinas all rejected the notion.
The St. Aquinas perspective:

While Aquinas denied she was sinless from the absolute moment of conception, he staunchly believed she was sanctified before her birth and thus never committed any actual personal sin.
The dogma of the Immaculate Conception had not yet been formally defined (it was defined in 1854). The debate was a major scholastic topic, with the Dominican tradition (including Aquinas) largely arguing against it, while the Franciscan tradition (led by Duns Scotus) later supported it.
Aquinas argued that the fetus must be "animated" (endowed with a soul) before it can be sanctified, placing her sanctification shortly after the initial act of conception.
In his early commentary on Peter Lombard’s Sentences, Aquinas stated that Mary was "immune from original and actual sin".
In his most famous work, the Summa Theologiae, he argued that Mary was sanctified in the womb after her conception. He feared that if she were conceived without sin, she would not have needed Christ’s redemption, which he believed was universal.
Because the Immaculate Conception was not defined as an infallible dogma until 1854 by Pope Pius IX, Aquinas was free to speculate during his lifetime. Today, most Dominican scholars and Catholic theologians believe that if Aquinas had access to later theological developments, he would have supported the dogma as it is now defined.
The St. Augustine perspective:

Augustine did not explicitly formulate or teach the modern dogma of the Immaculate Conception (that Mary was preserved from original sin from the moment of her conception). However, he laid significant groundwork by affirming her total sinlessness due to a unique grace, stating he would not discuss sin in relation to her out of honor for Christ.
Augustine firmly believed Mary was free from all actual sin. He wrote in Nature and Grace (415 AD) that he wished to exclude Mary completely from the conversation regarding sin, citing the "abundance of grace" she received.
.
Because of his high view of Mary's purity and his belief that she was the "New Eve" free from sin, he is often viewed as a forerunner to the later-defined doctrine of the Immaculate Conception, though he did not hold the precise theological definition.
Augustine’s focus was on her complete purity during the conception of Christ, rather than the state of her own conception, often referring to her as "all pure" while arguing that she, like all humans, required redemption by her Son.
Augustine upheld Mary's total sinlessness through grace but did not explicitly define her preservation from original sin, setting the foundation for the later, more defined doctrine.
he was a forerunner of the doctrine because he believed God's "abundance of grace" allowed her to "totally overcome sin".
Ultimately, while Augustine is seen as an early proponent of Mary's unique holiness, he did not explicitly articulate the Immaculate Conception in the specific terms later defined by the Catholic Church.
Augustine believed Mary was conceived with Original Sin but was perfectly cleansed by grace either at the moment of the Incarnation or shortly after her conception to prepare her to be the mother of Christ.
The St. Bernard perspective:

Bernard, influenced by Augustinian views on original sin, believed that sexual conception involved sin (concupiscence), making an immaculate conception impossible. Mary did not concieved through any sexual conception, but through the power of the Holy Spirit.
Instead of being immaculate at conception, Bernard believed Mary was sanctified in the womb after conception but before birth, similar to the view held later by Thomas Aquinas
St. Bernard maintained that Mary was sinless (without actual sin) throughout her life.
Blessed John Duns Scotus, who proposed the idea of "preservative redemption"—the idea that God saved Mary by preventing her from contracting original sin in the first place, rather than by removing it later. This explanation paved the way for the formal declaration of the dogma by Pope Pius IX in 1854.
Figures such as St. Irenaeus and St. Ephrem (4th century) referred to Mary as the "New Eve" and as being "all-holy" and "without stain".
The belief is derived from passages like Genesis 3:15 (the "enmity" between the woman and the serpent) and Luke 1:28, where the angel Gabriel addresses Mary as "kecharitōmenē"—often translated as "full of grace".
A feast for the "Conception of St. Anne" (Mary's mother) was celebrated in the Eastern Church as early as the 7th century.
My question is how do you explain Sirach 18:17, which uses the exact same word except in the masculine, but it is merely translated as a kind person?
“Indeed does not a word count more than a good gift?
Indeed does not a word count more than a good gift? But both are offered by a kind person. Sirach 18-17
Luke 1:28 and Sirach 18:17 are frequently compared because they both use the rare Greek verb charitoō ("to grace" or "to favor") in the perfect passive participle form.
Luke 1:28, which records the angel Gabriel’s greeting to Mary (“Hail, full of grace, the Lord is with you”), is often compared to Sirach 18:17, which discusses the behavior of a "gracious person." While they appear different on the surface, Catholic theology and scholarly analysis link them through themes of grace, divine favor, and the character of a person chosen by God.
"Full of Grace" (Greek: Kecharitomene): The Greek term indicates that Mary has already been, and continues to be, filled with grace by God. It is a unique title, with the root charitoo used to denote being highly favored or endowed with grace.
"The Lord is with you": This is interpreted as a statement of divine presence and favor (similar to the greeting to Gideon in Judges 6:12) rather than just a greeting, indicating God’s presence within her to fulfill her role as the Mother of God.
This verse is a primary biblical foundation for the Immaculate Conception, suggesting Mary was preserved from sin to be a perfect receptacle for Christ.
Sirach 18:17: The Gracious Person
Text: "Indeed does not a word count more than a good gift? But both are offered by a kind person." (NABRE) or "but both are with a justified man" (Douay-Rheims).
Sirach 18 discusses the nature of God, his mercy, and how a righteous or "gracious" (or "justified") person should act. It suggests that a person who is favored or in a state of grace (the "justified man") brings both good words and good deeds.
Some theologians connect the description of the "gracious person" in Sirach to Mary as the Kecharitomene—the woman who is completely filled with grace and who, through her "fiat" (word) and motherhood (gift), offers both a word and a gift to the world.
While Sirach speaks generally of a "justified man" (often interpreted as one who is gracious or "graced"), Luke 1:28 applies this state of being graced specifically to Mary in a unique, permanent way.
"Full" vs. "Gracious": Sirach 18 describes a person who has grace, whereas Luke 1:28 describes Mary as being entirely transformed by grace (filled with it).
Luke 1:28 (Greek: kecharitōmenē): The angel Gabriel addresses Mary as kecharitōmenē, a feminine perfect passive participle. This form suggests an action completed in the past with continuing effects in the present. In the Latin Vulgate, St. Jerome translated this as gratia plena ("full of grace").
Sirach 18:17 (Greek: kecharitōmenō): This verse describes a "gracious man" or "favored man" who gives both a kind word and a gift. The Greek uses the masculine form of the same participle.
Noun vs. Title: In Sirach 18:17, the word is used as an adjective to describe a type of person (a "gracious man"). In Luke 1:28, the word replaces Mary's name entirely, serving as a proper name or title. Many theologians argue this makes the usage in Luke unique, as it defines Mary’s very identity.
Nature of Grace: In Sirach, the "grace" often refers to a social or moral quality—being a pleasant or generous person. In Luke, it is widely interpreted by Catholic and Orthodox traditions as supernatural sanctifying grace from God.
Catholic theologians point to the perfect tense in Luke as biblical evidence for the Immaculate Conception, suggesting Mary was "filled with grace" from the first moment of her existence.
Protestant platforms argue that since a similar form appears in Sirach and Ephesians 1:6, it simply denotes being "highly favored" without implying sinlessness. The Question asked of me regarding the Immaculate Conception is coming from a cleaver Protestant who thinks he has me stumped
The Immaculate Conception is a Catholic dogma, defined by Pope Pius IX in 1854's Ineffabilis Deus, declaring that Mary was preserved free from all original sin from the moment of her conception by a unique grace of God. It is not the conception of Jesus, but rather highlights Mary's sinless nature, essential for her role as the Mother of God.
The dogma states that Mary was "preserved immune from all stain of original sin" by a unique grace from God. This was done "in view of the merits of Jesus Christ," meaning she was still redeemed by her Son, but in a "preventive" way rather than a "curative" one.
Mary was immaculately conceived without the stain of original sin, a grace foreseen by God to make her a suitable dwelling place for Jesus.
While not explicitly in the Bible, it is rooted in Scripture's "full of grace" (Luke 1:28) and the tradition of Mary as the "New Eve," as well as early Church reflections on her sinlessness.
This privilege, known as "preventative redemption," means Mary was saved by Christ in a more perfect manner, preserved from sin before it could take root, rather than cleansed from it later.
Proclaimed as a dogma by Pope Pius IX on December 8, 1854, in the apostolic constitution, Ineffabilis Deus.
It is often confused with the virginal conception of Jesus (Christmas) or the Annunciation, but refers specifically to Mary's own conception.
It is considered God's greatest act of mercy and is central to the Marian charism, and is related to the Dogma of the Assumption.
