Albert Barnes Commentary Ephesians 2:21

"in whom each several building, fitly framed together, groweth into a holy temple in the Lord;" — Ephesians 2:21 (ASV)

In whom. That is, by whom, or upon whom. It was in connection with him, or by being built on him as a foundation.

All the building. The whole church of Christ.

Fitly framed together. The word used here means to joint together, as a carpenter does the framework of a building. The materials are accurately and carefully united by mortises and tenons, so that the building will be firm. Different materials may be used, and different kinds of timber may be employed, but one part is worked into another to constitute a durable and beautiful edifice.

So it is in the church. The different materials of Jews and Gentiles, the people of various nations, though previously separated and discordant, now become united and form a harmonious society. They believe the same doctrines, worship the same God, practice the same holiness, and look forward to the same heaven.

Groweth unto an holy temple in the Lord (see Barnes on 1 Corinthians 3:17 and 2 Corinthians 6:16).
