Psalms 122:9

9.Because of the house of Jehovah our God, etc. In this verse he adds a second reason why he cared for the Church — that he did so, because the worship of God so far from remaining entire would go to ruin unless Jerusalem continued standing. If then the salvation of our brethren is regarded by us as an object of importance, if religion is with us a matter of heart-work, we ought, at the same time, as much as in us lies, to take an interest in the prosperity of the Church. Whence it follows, that such are indifferent about her condition, are no less cruel than impious; for if she is “the pillar and foundation of truth,” the inevitable consequence of her destruction must be the extinction of true piety. And if the body is destroyed, how can each of the members fail to be involved in destruction? Farther, this passage teaches us that the Church is not an empty title, but must be sought for where the true religion prevails. Whence it appears, how foolish the Papists are, who, notwithstanding their having rejected and overthrown the doctrine of the Gospel, yet mightily boast of the name of the Church.
