The Church at the same time was growing in material wealth through gifts from state resources of landed property or money and grain. Christians could not be forced to participate in pagan festivals. At the same time Christian influence brought about some mitigation in the punishment of criminals.
In addition to all this, Constantine's name is connected with the erection of many churches in all parts of his immense empire. The basilica of St. Peter and the basilica of the Lateran in Rome are ascribed to him. He was particularly interested in Palestine, where his mother, Helena, supposedly found the true cross. In Jerusalem, in the place where Christ was buried, the Church of the Holy Sepulchre was erected; on the Mount of Olives Constantine built the Church of the Ascension and at Bethlehem the Church of the Nativity. The new capital, Constantinople, and its suburbs were also adorned with many churches, the most prominent the Church of the Apostles and the Church of St. Irene; it is possible that Constantine laid the foundations of St. Sophia, which was completed by his successor, Constantius. Many churches were being constructed in other places during Constantine's reign, at Antioch, Nicomedia, and North Africa.
