In the early days of the Gospel, while the Christians were generally poor, and when they were obliged to meet in fear of the heathen, their worship was held in private houses, and sometimes in burial-places under-ground. But after a time buildings were expressly set apart for worship. It has been mentioned that in the years of quiet, between the death of Valerian and the last persecution (A.D. 261-303), these churches were built much more handsomely than before, and were furnished with gold and silver plate and other rich ornaments.[16] And after the conversion of Constantine, they became still finer and costlier. The clergy then wore rich dresses at service, the music was less simple, and the ceremonies were multiplied. Some of the old heathen temples were turned into churches; but temples were not built in a shape very suitable for Christian worship, and the pattern of the new churches was rather taken from the halls of justice, called _Basilicas_, which were to be found in every large town. These buildings were of an oblong shape, with a broad middle part, and on each side of it an aisle, separated from it by a row of pillars. This lower part of the basilica was used by merchants who met to talk about their business, and by all sorts of loungers who met to tell and hear the news. But at the upper end of the oblong there was a half circle, with its floor raised above the level of the rest; and in the middle of this part the judge of the city sat. Now if you will compare this description with the plan of a church, you will see that the broad middle part of the basilica answers to what is called the _body_ or _nave_ of the church; that the side _aisles_ are alike in each; and that the further part of the basilica, with its raised floor, answers to the _chancel_ of a church; while the _holy table_, or _altar_, stands in the place answering to the judge's seat in the basilica. Some of these halls were given up by the emperors to be turned into churches, and the plan of them was found convenient as a pattern in the building of new churches. [16] Page 32.
