Year A of the 3-Year Lectionary Cycle?

The Latins are currently on Year C.

I am guessing this reflection was written a while ago, for Year A.

Tale of Two Adams: Scott Hahn Reflects on the First Sunday of Lent

Formed from the clay of the ground and filled with the breath of God’s own Spirit, Adam was a son of God (see Luke 3:38), created in his image (see Genesis 5:1-3). Crowned with glory, he was given dominion over the world and the protection of His angels (see Psalms 8:6-8; 91:11-13). He was made to worship God—to live not by bread alone but in obedience to every word that comes from the mouth of the Father.

Is Adam (son) of God? It would seem so. But is he a son of God in the same way that we are, having been reborn in Christ in Baptism and Chrismation? I don't think so. I don't think anyone was an (adopted) son of God in the Son before the Incarnation. Or if the righteous of the Old Testament were to be accounted sons of God, their sonship or their adoption was incomplete, until Christ had conquered death and was risen?

As for the question of obedience, which Adam failed to give -- the obedience that is essential for us to the glorification of the Father, is that the same as the sacrifice of Christ, or is it a part or consequence of the sacrifice (and thus not wholly identical with sacrifice)?
