Wikipedia is not a recognized source of scholarly research. However, I have a Wikipedia site that has information that is consistent with legitimate sources available to me and is comprehensive and organized better than any other source. See http://en.wikipedia.org/wiki/Church_architecture for that source, as follows:
The church building as we know it grew out of a number of features of the Ancient Roman period:
- The house church
- The atrium
- The basilica
- The bema
- The mausoleum – centrally-planned building
- The cruciform ground plan – Latin or Greek cross
When Early Christian Communities began to build churches they drew on one particular feature of the houses that preceded them, the atrium, or courtyard with a colonnade surrounding it. Most of these atriums have disappeared. A fine example remains at the Basilica of San Clemente in Rome and another was built in the Romanesque period at Sant’Ambrogio, Milan. The descendants of these atria may be seen in the large square cloisters that can be found beside many cathedrals, and in the huge colonnaded squares or piazze at the Basilicas of St Peter’s in Rome and St Mark’s in Venice and the Camposanto (Holy Field) at the Cathedral of Pisa.
Early church architecture did not draw its form from Roman temples, as the latter did not have large internal spaces where worshipping congregations could meet. It was the Roman basilica, used for meetings, markets and courts of law that provided a model for the large Christian church and that gave its name to the Christian basilica.
Both Roman basilicas and Roman bath houses had at their core a large vaulted building with a high roof, braced on either side by a series of lower chambers or a wide arcaded passage. An important feature of the Roman basilica was that at either end it had a projecting exedra, or apse, a semicircular space roofed with a half-dome. This was where the magistrates sat to hold court. It passed into the church architecture of the Roman world and was adapted in different ways as a feature of cathedral architecture.
The earliest large churches, such as the Cathedral of San Giovanni in Laterano in Rome, consisted of a single-ended basilica with one aspidal end and a courtyard, or atrium, at the other end. As Christian liturgy developed, processions became part of the proceedings. The processional door was that which led from the furthest end of the building, while the door most used by the public might be that central to one side of the building. This is the case in many cathedrals and churches.
As numbers of the clergy increased, the small apse which contained the altar, or table upon which the sacramental bread and wine were offered in the rite of Holy Communion, was not sufficient to accommodate them. A raised dais called a bema formed part of many large basilican churches. In the case of St. Peter’s Basilica and San Paolo fuori le Mura (St Paul’s outside the Walls) in Rome, this bema extended laterally beyond the main meeting hall, forming two arms so that the building took on the shape of a T with a projecting apse. From this beginning, the plan of the church developed into the so-called Latin Cross which is the shape of most Western Cathedrals and large churches. The arms of the cross are called the transept.
