Yes, I agree it appears that the most obvious sense of the Genesis 2:7 text is that God formed Adam’s body from inanimate material, the ‘dust of the ground’, and then infused the rational soul into it which animates the body where it continues and ‘breathed into his nostrils the breath of life, and man became a living being’. The CCC also gives this interpretation to the last part of the text of 2:7 concerning the human rational soul. I don’t dispute this text of Genesis for I believe it to be literally true and that God miraculously and immediately created the first man Adam both as to soul and body as well as the first woman, Adam’s wife Eve, from Adam’s side or rib.
What I said about Jesus breathing on the disciples and saying to them ‘Receive the Holy Spirit’ and connecting this breathing to God breathing into the nostrils of Adam the breath of life is like an analogy of the former with the later, Jesus connecting the New Testament with the Old Testament as he is the author of both and confirming as it were the divine inspiration and truth of the Old Testament text. The quotes I gave above from St Irenaeus and St Augustine and the analogies they write about concerning the Old Testament with the New Testament follows this same sort of analogy I brought up about the ‘breathing’ concerning Adam’s creation and Jesus breathing on the disciples. There is also the analogy between the creation of Eve from the side of the sleeping Adam and the birth of the Church, the bride of Christ, from the sleeping Christ on the cross when he was pierced with a lance and out flowed blood and water, symbols of the two great sacraments of the Church, namely, the eucharist and baptism. All these analogies and figures of the Old Testament with the New Testament, the sacred writers of the Old Testament probably did not know, definitely without a divine revelation, would be fulfilled in some analogous manner in Christ and the New Testament. But God, the principle author of Sacred Scripture, was guiding their writing and so I see in all these analogies and figures of the Old Testament in the New Testament the divine inspiration and truth of the Old Testament scriptures whose principle author is God himself guiding the writing of the sacred human authors.
