Mohammedanism was a heresy: that is the essential point to grasp before going any further. It began as a heresy, not as a new religion. It was not a pagan contrast with the Church; it was not an alien enemy. It was a perversion of Christian doctrine. It vitality and endurance soon gave it the appearance of a new religion, but those who were contemporary with its rise saw it for what it was_not a denial, but an adaptation and a misuse, of the Christian thing.
Something very odd will be happening in the Vatican tomorrow. From Vatican Insider:
It will begin with three distinct prayers – Jewish, Christian and Muslim – the “prayer for peace” that will bring together, on Sunday evening in the Vatican gardens, Pope Francis, Israeli President Shimon Peres, the Palestinian Authority, Mahmoud Abbas (Abu Mazen) and the Orthodox Ecumenical Patriarch Bartholomew. It will be a “pause from politics” and the delegations, which are still incomplete, will not include representatives of the respective governments.
