Charles H. Spurgeon on Psalms 118:22

The stone which the builders refused. Here we behold with how strong and impregnable a shield the Holy Ghost furnishes us against the empty vaunting of the Papal clergy. Be it so, that they possess the name, "chief builders"; but if they disown Christ, does it necessarily follow that we must disown him also? Let us rather contemn and trample under our feet all their decrees, and let us reverence this precious stone upon which our salvation rests. By the expression, is become the head of the corner, we are to understand the real foundation of the church, which sustains the whole weight of the edifice; it being requisite that the corners should form the main strength of buildings. John Calvin.
