What does the Bible say about the church as a household?

The church is often referred to in Scripture as a household or family, highlighting the familial relationships among its members. For instance, in Ephesians 2:19, believers are described as fellow-citizens and members of the household of God. This metaphor underscores the care and responsibility that members have towards one another, as well as the love and unity that should characterize their interactions. Just as a functional family looks after one another, so should the church reflect this through mutual support and care for each member's spiritual needs.
