- The Assyrian Church, Catholics, Old Catholics (including those no longer or never in communion with Utrecht), Orthodox, Oriental Orthodox, Lutherans and most Sedevacantist Schismatics are the only ones who immediately and without reservation declare the real presence.
Some Anglicans profess belief in the real presence, while others tend towards the “pneumatic presence” taught by Reformed traditions. Still others even veer into Zwinglian territory. Methodists are likewise all over the place, not surprisingly, given their Anglican origins.
Reformed, Baptists, Pentecostals, etc almost invariably believe in nothing stronger than the pneumatic presence, though aside from that upper limit their positions vary from congregation to congregation.
- In Rome’s view, only the Catholics, Old Catholics, Orthodox, and Oriental Orthodox and the Sedevacantist Schismatics possess the real presence, as only these are believed to possess valid Holy Orders. There might be a conditional recognition of Anglican eucharists, especially if the Anglican priest in question is from a lineage originating with the Old Catholics or is a former Catholic priest.
From the viewpoint of the others, the Anglicans, Lutherans, and possibly Old Catholics are the most generous and would say all of them have it.
The Orthodox opinion can vary, some rigorist Orthodox believing that Latin orders have suffered a deficiency which renders sacraments invalid, while others recognize Roman orders and sacraments as valid even if illicit (basically the mirror of Rome’s view of them). Nevertheless whatever their view on Rome, Orthodox (without any exception I’ve ever met) consider Protestant sacraments invalid. Note though, Anglicanism presents a tricky subject here as everywhere.
The Oriental Orthodox are analogous to the Orthodox. Likewise for the Assyrian Church.
