And until the Council of Trent in 1054 there was a single Church, and it moved its seat of power to Constantinople.

The Council of Trent started in 1545, but what's this about the Church moving her seat of power to Constantinople?

[FromTheSidelines]

The seat of the Church moved when the power-mad Pope in Rome was excommunicated from the Church, in 1054. And it’s been that way ever since... The Roman Catholics are trying to come back to the Church, but their heretical beliefs (in particular, the Filioque, Papal primacy, original sin and others) prevent their rejoining the true Church.
