Irenaeus on why the Son became human
“He became what we are, that he might make us what he is.”
Plain English
Irenaeus is explaining the logic of the incarnation. The Son enters real human life so human beings can be restored to communion with God.
Why it matters
This is the seed of the later patristic theme of deification: salvation is participation in God's life, not merely pardon.
About Irenaeus
Irenaeus gave the church its first large-scale answer to the question, 'how do we know this is apostolic Christianity?' Against Gnostics, Marcionites, and private spiritual teachers, he argued from public scripture, public teaching, and the churches founded by the apostles. Apostolic succession in his hands was not just a power claim; it was a way of checking whether a teacher was inventing a new religion under Christian names. Later orthodoxy inherited that instinct from him.
