From an Easter sermon

The whole thing is worth reading  (from today's Office of Readings) but here's the conclusion of a sermon by St. Maximus of Turin, bishop:

And so, my brothers, each of us ought surely to rejoice on this holy day. Let no one, conscious of his sinfulness, withdraw from our common celebration, nor let anyone be kept away from our public prayer by the burden of his guilt. Sinner he may indeed be, but he must not despair of pardon on this day which is so highly privileged; for if a thief could receive the grace of paradise, how could a Christian be refused forgiveness?
