Catechesis: Holy Baptism

What is the old man? It is what is born in human beings from Adam: anger, hate, evil, unchastity, stinginess, laziness, arrogance—yes, unbelief. The old man is infected with all vices and has by nature nothing good in him. Now, when we have come into Christ’s kingdom these things must daily decrease. The longer we live the more we become gentle, patient, meek, and ever turn away from unbelief, greed, hatred, envy, and arrogance. This is Baptism’s true use among Christians.—LC IV:66-68
