3. Irenaeus’ Anthropology and Ethics in his Demonstration of the Apostolic Preaching
In his introductory section of his Irenaeus provides us with a brief summary of his anthropology and his understanding of ethics that flows from that. From my recent reading, it seems generally accepted that Irenaeus held to a body-soul composition of all people, and that only believers have a body-soul-spirit. The spirit is comes from an experience of God’s Spirit. This is in opposition of Gnostics who saw some as by nature with spirit (pneumatics) and those who by nature only had a soul (psychics).
2. Now, since man is a living being compounded of soul and flesh, he must needs exist by both of these: and, whereas from both of them offences come, purity of the flesh is the restraining abstinence from all shameful things and all unrighteous deeds, and purity of the soul is the keeping faith towards God entire, neither adding thereto nor diminishing therefrom. For godliness is obscured and dulled by the soiling and the staining of the flesh, and is broken and polluted and no more entire, if falsehood enter into the soul: but it will keep itself in its beauty and its measure, when truth is constant in the soul and purity in the flesh. For what profit is it to know the truth in words, and to pollute the flesh and perform the works of evil? Or what profit can purity of the flesh bring, if truth be not in the soul? For these rejoice with one another, and are united and allied to bring man face to face with God. Wherefore the Holy Spirit says by David: Blessed is the man who hath not walked in the counsel of the ungodly: that is, the counsel of the nations which know not God: for those are ungodly who worship not the God that truly is. And therefore the Word says to Moses: I am He that is; but they that worship not the God that is, these are the ungodly. And hath not stood in the way of sinners: but sinners are those who have the knowledge of God and keep not His commandments; that is, disdainful scorners. And hath not sat in the seat of the pestilential:< now the pestilential are those who by wicked and perverse doctrines corrupt not themselves only, but others also. For the seat is a symbol of teaching. Such then are all heretics: they sit in the seats of the pestilential, and those are corrupted who receive the venom of their doctrine.
