The word "body" is used both as figuratively and as literally.
As an assembly, the church represents Christ. The members of the church reflect the gifts of which the ministry is complete. This is as if the literal physical body of Christ were present (as it was and will be) on the earth. All that Christ represented in the physical ministry, He bestows upon individuals in the assembly and as a collective they figuratively display the body of Christ.
Therefore, figuratively when the body of Christ is mentioned as the church, it is the assembly in this current form and use.
However, the assembly is presented to God as the Bride of Christ. As such, the physical presence of the Son is no longer figuratively represented, because the groom is with the bride in a literal meaning. Once the members of the body are transformed into their glorious form (for it does not appear what we shall be but we shall be like Him) the "body of Christ" is not mentioned, but the Bride of Christ.
