7 These things, beloved brethren, when we have learned from the sacred reading, and have gathered in what way we ought to approach to prayer, let us know also from the Lord's teaching what we should pray. “Thus,” says He, pray:—
“Our Father, who art in heaven, Hallowed be Your name. Your kingdom come. Your will be done, as in heaven so in earth. Give us this day our daily bread. And forgive us our debts, as we forgive our debtors. And suffer us not to be led into temptation; but deliver us from evil. Amen.”
