Then came Peter to him, and said, Lord, how often shall my brother sin against me, and I forgive him? till seven times?
All Commentaries on Matthew 18:21 Go To Matthew 18
Augustine of Hippo
AD 430
What then does “seventy times seven” mean? Listen, my friends, to this great mystery, this wonderful gift. When the Lord was baptized, Luke the holy Evangelist there noted down his ancestry, in what order, series and stems that generation had been reached in which Christ was born. Matthew began from Abraham and came as far as Joseph in descending generations. But Luke began to count by going back up in ascending order. Why does the one reckon in a descending and the other in an ascending order? Because Matthew set forth the generations of Christ by which he came down to us, and so he began to reckon when Christ was born from a descending order. Luke begins to reckon in reverse from when Christ was baptized. In this is the beginning of an ascension, for he begins to reckon in an ascending order. Note that in his account he enumerates seventyseven generations! With whom did he begin his reckoning? Note carefully! He began to reckon from Christ up to Adam himself, who was the first sinner and who parented us into bondage to sin. Luke reckoned up to Adam, and so there are enumerated in toto seventyseven generations—from Christ up to Adam and from Adam up to Christ. Note seventyseven! So then if no generation was omitted, there is no exemption of any trespass that ought not to be forgiven. For therefore did he reckon up his seventyseven generations, which number the Lord mentioned as to the forgiveness of sins; since he begins to reckon from the baptism, where all sins are remitted.
