Irenaeus

Today we celebrate Saint Irenaeus

‘So also by the obedience of one man, righteousness having been reintroduced, shall cause life to fructify in those persons who in times past were dead…so did he who is the Word, recapitulating Adam in himself, rightly receive a birth, enabling him to gather up Adam (into himself) from Mary.’ (3.21.10)
‘Luke points out that the pedigree which traces the generation of our Lord back to Adam contains seventy-two generations connecting the end with the beginning, and implying that it is he who has summed up in himself all nations dispersed from Adam downwards.’ (3.22.3)
For if He be not the God of the dead but of the living, yet was called the God of the Fathers who are sleeping, they do indubitably live to God, and have not passed out of existence, since they are children of the resurrection. But the fathers are his children for (Ps 45.17) ‘Instead of thy fathers, thy children have been made to thee’.. For Abraham according to his faith followed the command of the Word of God and with a ready mind delivered up as a sacrifice to God his only begotten and beloved son, in order that God might also be pleased to offer up for all his seed his own beloved and only-begotten Son as a sacrifice for our redemption. (4.5.4) Against the Heresies
