“Give us this day our daily bread.”
Matthew 6:11 — Greek Interlinear
Church Fathers on Matthew 6:11
These three things therefore which have been asked in the foregoing petitions, are begun here on earth, and according to our proficiency are increased in us; but in another life, as we hope, they shall be everlastingly possessed in perfection. In the four remaining petitions we ask for temporal blessings which are necessary to obtaining the eternal; the bread, which is accordingly the next petition in order, is a necessary.
The Greek word here which we render, 'supersubstantialis,' is επιουσιος . The LXX often make use of the word, περιουσιος , by which we find, on reference to the Hebrew, they always render the word, sogola. [ed. note, c: סגלה on επιουσιος , vid. note c on Cyr. Cat. xxiii. 15. Tr. and Petav. Dogm. t. iv. pp. 200,201. ed. Antwerp. 1700.]
For Christ is the bread of life, and this bread belongs not to all men, but to us. This bread we pray that it be given day by day, lest we who are in Christ, and who daily receive the Eucharist for food of salvation, should by the admission of any grievous crime, and our being therefore forbidden the heavenly bread, be separated from the body of Christ. Hence then we pray, that we who abide in Christ, may not draw back from His sanctification and His body.
