The answer is: Corinthians

2 Cor 6:18

In 2 Corinthians 6:18, when Paul expresses God’s desire to adopt believers as His sons and daughters, he speaks to the Christian community in Corinth. This letter reaches out to a group struggling with issues of identity, morality, and their place in a pagan society while navigating the idea of what it meant to follow Christ. It's a rich interchange of personal relationship and covenant—a connection that takes on the characteristics of a familial bond.

The invocation of “Father” is noteworthy, especially in Jewish tradition where the concept of God as a father is profound yet complex. While typically reserved for that sovereign, untouchable relationship, Paul here extends it to suggest a much more approachable God, signaling His openness to a Stateside familial kleos or kinship too.

Furthermore, God adopting us into His family echoes other Bible sequences wherein others like Moses, David, and even the Israelites are treated as God’s chosen ones; they too enjoyed this intimate familial understanding with the divine. This reminder carries implications of love, discipline, and inheritance—A powerful combination reflecting the dynamics of fatherhood.

Interesting trivia: the term “beloved” in many contexts is linked to the notion of love’s embrace, which can broaden our understanding of our relationship with the divine! It’s a heartfelt dynamic remembered during communal practices like sharing meals together or intercessory prayer, demonstrating unity and belonging within a familial-like community. Paul was not only misconstruing theology but warmly inviting the Corinthians into an urgent familial bond.
