Luke 3:21

The motive of his baptism, as he himself informs us, was, that he himself might fulfil all justice. What is here meant by justice, but that obligation of doing first ourselves what we wish others to do? --- Let not one then refuse the laver of grace, since Christ did not refuse the laver of penance. (St. Ambrose) --- Although all our sins are forgiven in baptism, still the frailty of the flesh is not yet perfectly strengthened. For, after passing the red sea, we rejoice at the destruction of the Egyptians, but still we must fight with assurance of the grace of Christ, against the enemies we shall undoubtedly meet with in the desert of this world, till at length we arrive at our true country. (Ven. Bede) --- It is said the heavens were opened, because they had been hitherto shut. The sheepfolds of heaven and earth are now untied under the one Shepherd of the sheep: heaven is opened, and man, though formed of the earth, is admitted to the company of angels. (St. John Chrysostom)
