I never claimed that 5he Father, Son, and Spirit dwelled in Jesus' body. I am saying that the One God dwells bodily in Christ. I would even say the Godhead. But not the individual Persons of the Godhead.Again, quite a choice of words. You did not say the fullness of God dwells BODILY in the Son. Why is this important? Because the Son existed both prior and after the incarnation but the "bodily" aspect did not. So what is the container for the Godhead prior to the existence of a body? If the whole entire Godhead (Father, Son and Spirit) dwelt in bodily form rather than the entire attributes (pleroma) that make God to be God then how can you escape the obvious conclusion to that line of thinking that the entire Godhead (Father, Son and Spirit) continue to dwell in a body rather than just the Son of God? Either the term "Godhead" includes all three Persons or it does not. If the meaning is only the PLEROMA or all attribues that make God to be God, whether in the Father, or in the Son or in the Spirit dwell within the body of Christ that is one thing but to claim the Father, Son and Spirit dwell in the body of Christ is quite another thing.
In other words, there is NOTHING of God that exists outside of the Son (or the Father, or the Spirit). The Father and Son are One.
