Chapter 11 — Part I — Article IX (Of the Church)
Section 254. Q. How can the Church, which is visible, be the object of faith, when faith, as the Apostle says, is the evidence of things not seen? A. First, though the Church be visible, the grace of God, which dwells in her, and in those who are sanctified in her, is not so; and this it is which properly constitutes the object of faith in the Church. Secondly, the Church, though visible so far as she is upon earth, and contains all Orthodox Christians living upon earth, still is at the same time invisible, so far as she is also partially in heaven, and contains all those that have departed hence in true faith and holiness.
