From the Lenten Triodion:
Friday of The First Week
Let us receive the proclamation of Lent with joy! For if our forefather Adam had kept the Fast, we would not have been deprived of Paradise. The fruit which killed us was beautiful to see and good to eat, so let us not be fooled by our eyes, for after food is eaten, it is worthless. Let us flee from intemperance, so that we may not be conquered by passions after having our fill. Let us sign ourselves with the blood of the one who, for our sake, was voluntarily led to death, so that the destroyer might not touch us. So we will partake of the Sacred Pascha of Christ for the salvation of our souls. (Matins Apostika)
