The origin of the prayer "Anima Christi" is uncertain, however, the prayer itself can be traced to go back to the 14th century through popular devotions. St. Ignatius Loyola (October 23, 1491 - July 31, 1551), a Spanish priest and founder of the "Society of Jesus" became a key proponent for the Anima Christi prayer.
Consider who St. Ignatius was, his history. At one time he was a man of power, he was a Soldier who had a different mindset that is common among those whose pride can cause a person to fall away from God. He grew up with much pride wanting to be famous, not for being a religious, but for being a Soldier immolating El Cid, the Knights of Camelot, and other popular stories at the time.
St. Ignatius had developed a skill with the sword winning a number of duels once killing a Moor who denied the Divinity of Christ. He was also known as a womanizer, he was a man who was pursuing his own hopes and dreams.
However, in St. Ignatius case, the Lord had a different plan. He was wounded at the Battle of Pamplona when a cannonball ricochet off a wall he was near shattering his right leg. While he was recovering, Ignatius began reading the lives of the Saints and spiritual works which transformed his life.
With a transformed life, St. Ignatius began using that fire from within that he had for personal glory and turned his whole being to promoting the Glory of God. At some point, the Anima Christi caught is eye and he placed this prayer in his classic writing, "Spiritual Exercises" that helped popularize the prayer.
The Anima Christi goes as follows:
Soul of Christ, sanctify me. Body of Christ, save me. Blood of Christ, inebriate me. Water from the side of Christ, wash me. Passion of Christ, strengthen me. O good Jesus, hear me. Within Thy wounds hide me. Separated from Thee let me never be. From the malignant enemy, defend me. At the hour of death, call me. And close to Thee bid me. That with Thy saints I may be Praising Thee, forever and ever. Amen.
The prayer follows the importance of Jesus "Bread of Life Discourse" found in the Gospel of St. John (6:51-59). At Mass we receive the actual Body, Blood, Soul, and Divinity of Jesus recognizing Jesus real presence in the Eucharist.
Before a Soldier goes into battle, it is important to prepare oneself before hand giving them the necessary aid to fulfill the mission. Taking that mindset recognizing the great need we have for Jesus in fighting the battle of life, the Anima Christi implores what is necessary to be sanctified, to be saved, to be inebriated, to be washed, and to be strengthened. Jesus who loves us without measure, does hear us, does hide us keeping us close to himself. Jesus is our Deliverer and our Protector from the evil one.

On January 29, 1890 Catholic Convert, Cardinal Newman referred to the Anima Christi as his creed with a little unique translation:
“Soul of Christ, be my sanctification;/ Body of Christ, be my salvation;/ Blood of Christ, fill all my veins;/ Water of Christ’s side, wash out my stains,/ Passion of Christ, my comfort be,/ O good Jesus, listen to me/ In Thy wounds I fain would hide/ Ne’er to be parted from Thy side;/ Guard me should the foe assail me;/ Call me when my life shall fail me./ Bid me come to Thee above,/ With Thy Saints to sing Thy love,/ World without end. Amen”
The Anima Christi is a great prayer for the Spiritual Warrior who often finds themselves out on the perimeter fighting the battle keeping the faith.
