Wrong! Nothing you posted proves this wrong
Also,Nothing you posted in the writings of a few Church fathers denied adoption is united with the love of God like I said , nor did they say anything about possibly falling from that love.
Sorry, dear brother , but you're grasping at straws.
Not at all. Even the word "adopt" is inconsistent with your explanation that adoption is "united with the love of Christ". It is more than that. Adoption is a legal term of ownership:
1. to choose or take as one's own; make one's own by selection or assent: to adopt a nickname.
2. to take and rear (the child of other parents) as one's own child, specifically by a formal legal act.
3. to take or receive into any kind of new relationship: to adopt a person as a protégé.
Heb 12:5 And have you forgotten the exhortation that addresses you as sons? "My son, do not regard lightly the discipline of the Lord, nor be weary when reproved by him. Heb 12:6 For the Lord disciplines the one he loves, and chastises every son whom he receives."

the placing as a son, that is, adoption (figuratively Christian sonship in respect to God): - adoption (of children, of sons).
A description is introduced of the Justification of the impious, and of the Manner thereof under the law of grace. By which words, a description of the Justification of the impious is indicated,-as being a translation, from that state wherein man is born a child of the first Adam, to the state of grace, and of the adoption of the sons of God, through the second Adam, Jesus Christ, our Saviour. And this translation, since the promulgation of the Gospel, cannot be effected, without the laver of regeneration, or the desire thereof, as it is written; unless a man be born again of water and the Holy Ghost, he cannot enter into the Kingdom of God.
Has the Church lost it's understanding of what "adopt" means?
