An excerpt from one of the Precommunion prayers:
http://www.myriobiblos.gr/texts/english/prayerbook/cont1.htm#21That with a clean heart,
Trembling mind
And contrite spirit
I may partake of Thy pure
And all-holy Mysteries
By which all who eat and drink Thee
With sincerity of heart
Are quickened and deified.
For Thou, my Lord, hast said:
"Whoever eats My Flesh
And drinks My Blood
Abides in Me
And I in Him."Wholly true is the word
Of my Lord and God.
