:::I wasn't using the term excommunicate in its most accurate theological term but in the effect it had on the relationship between the Pope and the Church of England. By declaring the Pope had no authority in England, they were effectively repudiating his temporal and spiritual authority. The Thirty Nine Articles reiterated this in 1563. So the final split with Rome, from the English POV was 1558, perhaps Rome hoped for a reconciliation for a few years but a one-sided relationship does not a marriage make.
