Pax:
We are indeed God’s children by way of adoption and creation.

Excellent posts. Please allow me to add some comments to what you have posted.
The fall destroyed our relationship with God, while Jesus restored it.
Jesus did more than just restore a relationship that Adam and Eve had with God before the Fall.
Adam and Eve lived in
friendship with God before the Fall. But they were predestined to an even greater glory – the glory of becoming fully divinized
children of God that would partake of the divine nature of God.**Catechism of the Catholic Church
MAN IN PARADISE
384** Revelation makes known to us the state of original holiness and justice of man and woman before sin: from their
friendship with God flowed the happiness of their existence in paradise.
374 The first man was not only created good, but was also established in friendship with his Creator and in harmony with himself and with the creation around him, in a state that would be
surpassed only by the glory of the new creation in Christ.
**398 ** … Constituted in a state of holiness, man was destined to be **fully “divinized” ** by God in glory.
**381 ** Man is predestined to reproduce the image of God’s Son made man, the “image of the invisible God” (Col 1:15), so that Christ shall be
the first-born of a multitude of brothers and sisters (cf. Eph 1:3-6; Rom 8:29).
The following passage speaks beautifully to our adoption:
1 John 3:1-2
SEE WHAT love the Father has given us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him. Beloved, we are God’s children now …
A Catholic in a state of sanctifying grace is in a
higher state of grace than that possessed by Adam and Eve before the Fall - “we are God’s children
now”.**Catechism of the Catholic Church
Risen with Christ
1002** Christ will raise us up “on the last day”; but it is also true that, in a certain way, we have already risen with Christ. For, by virtue of the Holy Spirit, Christian life is already now on earth a participation in the death and Resurrection of Christ …
1003 United with Christ by Baptism,
believers already truly participate in the heavenly life of the risen Christ, but this life remains “hidden with Christ in God.” The Father has already “raised us up with him, and made us sit with him in the heavenly places in Christ Jesus.” Nourished with his body in the Eucharist, we already belong to the Body of Christ. When we rise on the last day we “also will appear with him in glory.”
