“For Christians to be linked in association with ministers who do not preach the gospel of Christ is to incur moral guilt. A union which can continue irrespective of whether its member churches belong to a common faith is not fulfilling any scriptural function. The preservation of a denominational association when it is powerless to discipline heretics cannot be justified on the grounds of the preservation of ‘Christian unity.’ It is error which breaks the unity of churches, and to remain in a denominational alignment which condones error is to support schism.”

The Forgotten Spurgeon, Murray, 164-165.

One thing is clear to us, we cannot be expected to meet in any union which comprehends those whose teachings on fundamental points is exactly the reverse of that which we hold dear. Cost what it may, to separate ourselves from those who separate themselves from the truth of God is not alone our liberty but our duty.”

The Sword and Trowel.

“Separation from such as connive at fundamental error, or withhold the ‘Bread of life’ from perishing souls, is not schism, but only what truth, and conscience, and God require of all who would be found faithful.”

The Sword and Trowel, 127.
