After Mass

O Master,
Christ our God,
King of the ages, and maker of all things:
I thank thee for all the good things which thou hast bestowed upon me,
and for this partaking of thine immaculate and life-giving Mysteries.
Wherefore I pray thee, who art good and lovest mankind:
Keep me under thy protection, and in the shadow of thy wings;
and grant unto me with a pure conscience and even unto my last breath,
to partake of thy holy Mysteries,
unto remission of sins and unto life everlasting.
For thou art the Bread of Life, the Fountain of holiness,
the Giver of good things, and unto thee we ascribe Glory:
to the Father, and to the Son, and to the Holy Spirit;
now and ever, and unto ages of ages. Amen.

St Basil the Great (329-379)
