We should never forget that Christ was handed over for our transgressions, and rose again for our justification. We are reminded of this by these days of such marvelous grace, in which by celebrating solemnly every year what happened once and for all, we are not allowed to forget it...Christ suffered, let us die to sin; Christ rose again, let us live for God. Christ passed over from this world to the Father; don't let our hearts stick here below, but rather follow to the realms above. Our head hung on the tree, let us crucify the lust of the flesh. He lay in the tomb; buried with him, let us forget the past. He is seated in heaven, let us transfer our desires to sublime realities. He is going to come as judge, let us not bear the yoke with unbelievers. He is also going to resuscitate the corpses of the dead; let us deserve this transfiguration of the body by a transformation of our minds. He is going to set the bad on his left, the good on his right; let us choose our place with good works. His kingdom will have no end; let us fear the end of this life not a whit. All the instruction of our peace is in him, by whose bruises we have been healed.
~St. Augustine, Sermon 229D, 1-3
