While it is true that the family and the local church are distinct jurisdictions with distinct spiritual responsibilities, the Scriptures unite the mission of the church and the family in specific ways.
As noted above, one of the fundamental purposes of the church is to equip believers for ministry. The local church must equip believers, including parents and children, by teaching them to honor their parents (Ephesians 6:2), love their spouses and children (Ephesians 5:25, Titus 2:4), and make disciples of their children and grandchildren (Deuteronomy 6:5-7, Psalm 78:1-7, Ephesians 6:4).
Not only does the local church equip believers for ministry in and to their family members, but in the Old Testament, families came together for worship and remembering God’s faithfulness (Exodus 12:21-28, Deuteronomy 16:9-11). Furthermore, in the New Testament whole households experienced spirituality together (Acts 11:14, 16:14-15, 16:29-31, 18:7-8, 1 Corinthians 1:16).
