Anima Christi

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.
Never let me be separated from Thee.
From the wicked foe, defend me
And at the hour of my death,
Call me and bid me come to Thee,
That with Thy angels and saints
I may praise Thee forever in eternity. Amen.

A favorite prayer of St. Ignatius of Loyola; author unknown; dates from the 14th-century (Wikipedia).

Latin

Anima Christi

Ánima Christi, sanctífica me.
Corpus Christi, salva me.
Sanguis Christi, inébria me.
Aqua láteris Christi, lava me.
Pássio Christi, confórta me.
O bone Iesu, exáudi me.
Intra tua vúlnera abscónde me.
Ne permíttas me separári a te.
Ab hoste malígno defénde me.
In hora mortis meæ voca me.
Et iube me veníre ad te,
ut cum Sanctis tuis laudem te
in sæcula sæculórum. Amen
