While no family is without some level of disfunction, those whose experience of family has left them hurt and alienated can experience what family is truly meant to be as part of the church.
It’s one of the reasons I look forward to gathering with Christians week by week:
From Derek Thomas:
…the church is an assembly called together into a homogenous, integrated unity. Several perspectives reinforce this in the New Testament. The church comprises the “family of God.” Each member of the church has become an “adopted son” (huiothesia; Rom. 8:15; 9:4; Gal. 4:5; Eph. 1:5). Now we are “members of the household of God” (Eph. 2:19), in which Jesus Christ is our elder brother. Jesus is not ashamed to call us brothers (Heb. 2:11). We come to God in prayer, saying, “Our Father” (Matt. 6:9). To those whose experience of family is dysfunctional in this world, the experience of belonging to a community of brothers and sisters is redemptive and restorative, particularly when they experience the loving concern (fellowship [koinōnia]) of “those who are of the household of faith” (Gal. 6:10).
