Do Catholics eat the substance of the Father during "communion"?

The reason I am raising this question is not so much to understand communion as to understand: * "one substance with the Father" (since that seems at odds with Hebrews 1:1-3 to me) * "consubstantiation" * "transubstantiation" My thought is by understanding this specific I might have a better idea of what they might mean. So if someone eats Jesus' body does "same substance", "consubstantiation" or "transubstantiation" suggest that Catholics are they eating the Father's substance? Again, these are probably ignorant questions but the answers might clarify for me what the Catholic theologians are on about.
