The church was founded by our Lord on the prophets and apostles, being himself the chief corner-stone. This is asserted here as a simple historical fact. Historically, the church has existed, without any break or defect of continuity, from the apostles down to our times. Its unbroken existence from that time to this cannot be questioned. It has been a fact during all that period in the world's history, and too momentous a fact to escape observation. Indeed, it has been the one great fact of history for over eighteen hundred years; the central fact around which all the facts of history have revolved, and without which they would be inexplicable and meaningless. This assumed or granted, it must be conceded that she unites as one continuous fact, in one body, the apostles and the believers of to-day. She is a continuous fact; a present fact during all the period of time that has elapsed between the apostles and us, and therefore is alike present to them and to us. Her existence being unbroken, she has never fallen into the past; never been a past fact; but has always been and is a present fact; and therefore as present with the apostles to-day as she was on the day of Pentecost, when they received the Holy Ghost; and therefore presents us not simply what they taught, but what they teach her now and here. She bridges over the abyss of time between our Lord himself and us, and makes us and the apostles, so to speak, contemporaries; so that, as it is our Lord himself we hear in the apostles, so it is the apostles themselves that we hear in her.
