Transubstantiation: bread and wine become Body and Blood of Christ
Consubstantiation: bread and wine coexist with Body and Blood of Christ
Honestly, these two beliefs do not seem to me to be insurmountably irreconcilable. As Catholics, we believe that the Eucharist remains “bread and wine” in “accident” or “appearance” - so in a way, the bread and wine DO co-exist with the body and blood of Christ, at least physically speaking. Metaphysically and “really” the bread and wine cease to exist - but my point is physically they do still exist. I believe it would be possible to reconcile transubstantiation with consubstantiation and synthesize them in a way acceptable to both Catholics and Anglicans.
I think if Anglican and Catholic theologians got together and hammered out this issue, we could probably come to a common declaration of faith regarding the Eucharist.
@FrDavid96 Does a declaration like this exist already?
