The "body of Christ" according to Ephesians 1:23, is the fulness of him that filleth all in all (Colossians 2:9) The one that filleth all in all is God (1 Corinthians 12:6; Ephesians 4:6, Acts 17:28).
The church, is Jesus' body, and all members as one body (including Jesus who is the Head- Colossians 2:9), is for a habitation of God (God dwells in the body of Christ) through his Spirit (Acts 2:22-39). In Ephesians 5 the way of marriage is described while speaking of Christ and the church, we are members of his flesh and of his bones just like a married man and woman are one flesh- Genesis 2:21-24, Matthew 19:3-6, Mark 10:4-9, Ephesians 5:22-33, Read it here: Ephesians 1:17-23, Ephesians 2:13-22, 1 Corinthians 12:12-14, Ephesians 4:4. Yes, God's building is the church. The body of Christ. In the man Jesus dwells the fulness of the Godhead bodily, it is not stating that Jesus IS the Godhead or that he is In the Godhead. Only that the fullness of the deity dwells IN him bodily, not stating that he is the deity- Colossians 2:9,
1 Corinthians 3: 6-11, 16-17.
We belong to Christ and Christ belongs to God-1 Corinthians 3:23. Christ is the Head of men, and the Head of Christ is God. Here is a demonstration of God's design in the scriptures: 1 Corinthians 11:3.

Jesus is Lord to the glory of God, the Father. Jesus is the one that was manifested and was received up into glory (1 John 3:8, 1 Timothy 3:16). Our Master did ascend to his Father and God as he told the woman Mary he was going to do in the book of John-John 20:16-17.
