Christ’s sacrifice was a sacrifice of flesh, Thomas admits, but he goes on to say that it was a suitable sacrifice because it was God’s own sacrifice.

The thought appears to be this: The Son takes our flesh, and by His sacrifice (which includes death and resurrection for Thomas) He takes that flesh up into the communion of Father and Son. Our flesh becomes an acceptable offering by being made the Son’s offering to the Father.

Because we are united to the Son by the Spirit, our self-offerings are also taken up and become part of the Son’s eternal self-offering to teh Father.
