All that Dr. Newman has so excellently said about development applies here legitimately and fully. Existence justifies additions and stages in existence. The living edifice planted on the foundation, _Let every one that nameth the name of Christ depart from iniquity_, could not but grow, if it lived at all. If it grew, it could not but make developments, and all developments not inconsistent with the aim of its original foundation, and not extending beyond the moral and practical sphere which was the sphere of its original foundation, are legitimated by the very fact of the Church having in the natural evolution of its life and growth made them. A boy does not wear the clothes or follow the ways of an infant, nor a man those of a boy; yet they are all engaged in the one same business of developing their growing life, and to the clothes to be worn and the ways to be followed for the purpose of doing this, nature will, in general, direct them safely. The several scattered congregations of the first age of Christianity coalesced into one community, just as the several scattered Christians had earlier still coalesced into congregations. Why?--because such was the natural course of things. It had nothing inconsistent with the fundamental ground of Christians, _Let every one that nameth the name of Christ depart from iniquity_; and it was approved by their growing and enlarging in it. They developed a church-discipline with a hierarchy of bishops and archbishops, which was not that of the first times; they developed church-usages, such as the practice of infant baptism, which were not those of the first times; they developed a church-ritual with ceremonies which were not those of the first times;--they developed all these, just as they developed a church-architecture which was not that of the first times, because they were no longer in the first times, and required for their expanding growth what suited their own times. They coalesced with the State because they grew by doing so. They called the faith they possessed in common the _Catholic_, that is, the general or universal faith. They developed, also, as we have seen, dogma or a theological philosophy. Both dogma and discipline became a part of the Catholic faith, or profession of the general body of Christians.
