That is not surprising; both denominations are post Reformation. Had the Reformation been fruitful, there would be one Church. Instead, we have tens of thousands of churches that claim to be christian. Christ wanted us to be one (John 17:22-23). We are all as a Church to be of one mind and to think the same (Philippians 2:2; Romans 15:5). There is only to be one "faith" (Ephesians 4:3-6), not many. For the Church is Christ's Body and Christ only had one Body, not many. Also, since the Church is Christ's Bride (Ephesians 5:29), can Christ be married to more than one wife (essentially a spiritual form of the the sin of polygamy)? No, Christ can only have one wife (i.e., one Church, not many).
That number keeps deflating, I see - and we're back to "churches" again! "Had the Reformation been fruitful"...and in a Catholic Caucus post, no less.
