Chapter II. The Unity Of The Church. 27 it is with material bodies, which, as time goes on, pass through successive phases of growth and development and multiply their years, but yet remain always the same individual bodies as they were in the beginning.... It very properly follows from the nature of things that, with a perfect agreement and consistency between the beginnings and the final results, when we reap the harvest of dogmatic truth which has sprung from the seeds of doctrine sown in the spring-time of the Church's existence, we should find no substantial difference between the grain which was first planted and that which we now gather. For though the germs of the early faith have in some respects been evolved in the course of time, and still receive nourishment and culture, yet nothing in them that is substantial can ever suffer change. The Church of Christ is a faithful and ever watchful guardian of the dogmas which have been committed to her charge. In this sacred deposit she changes nothing, she takes nothing from it, she adds nothing to it." [016]
