The second reading in today's Office of Readings of the Liturgy of the Hours (see the seventh section, Celebrating Hours, at this link) included this sentence from Pope St. Leo the Great of the fifth century:
The special note of the paschal feast is this: the whole Church rejoices in the forgiveness of sins. It rejoices in the forgiveness not only of those who are then reborn in holy baptism but also of those who are already numbered among God’s adopted children.Lent's emphasis on baptism is clearly not new. Its recovery benefits us by helping us to celebrate our baptismal vocations.
