As the Roman church had for centuries, Aquinas held that it is a true sacrifice, continuing that of Christ on the cross, and predisposing God to be gracious to those for whom it is offered. In the Supper the essence of the bread and wine are changed miraculously into the actual body and blood of Christ while the exterior remains unchanged, a doctrine known as transubstantiation—of which Thomas gave the classic presentation.
After successfully repulsing the Muslim armies in their second major attack on Constantinople (717–18), Leo openly declared his opposition to icons for the first time. An angry mob murdered the official who was sent to replace the icon of Christ with a cross over the Bronze Gate. Whole sections of the empire rebelled vigorously. Mosaics were gouged from the walls; icons were daubed with whitewash. Leo secured the retirement of the patriarch of Constantinople and the consecration of a new one who favored Leo’s views. The iconoclasts (or image breakers) wanted to replace the religious icons with the traditional Christian symbols of the cross, the Book (Bible), and the elements of the Lord’s Supper. These objects alone, they insisted, should be considered holy.
Three sins in particular—sexual immorality, murder, and the denial of the faith (apostasy)—were considered forgivable by God, but never by the church. The penalty for any one of these was exclusion from the fellowship of the church and deprivation of the Lord’s Supper.
The charge of cannibalism probably started because the Lord’s Supper was practiced in secret. The heathen did not know what happened at these closed meetings, but they heard that somebody was being eaten. Jesus had said at the Last Supper, “This bread is my body. This cup is my blood.” The pagans concluded that the Christians must be eating and drinking human flesh and blood.
Menkıbeye göre, Adem Cennet'i gezerken bir kubbe görür. İçine girdiğinde orta yerde bir tahtın üstünde dünya güzeli bir kadın oturduğunu görür. Kadının kafasında taç, belinde kemer ve kulaklarında iki küpe vardır. Adem kim olduğunu sorar, kadın kendi soyundan gelecek ahir zaman nebisinin kızı olduğunu söyler. Adem taç, kemer ve küpeleri sorar, kadın "başımdaki taç atam Muhammed Mustafa'dır; belimdeki kemer ehlim Ali el-Murtaza'dır; kulaklarımdaki küpeler şepper şüpper çocuklarım Hasan ve Hüseyin'dir; bizler dünyanın ahirinde senin sulbünden geleceğiz,"
