Matthew 18:9

This sentence of the Lord can faithfully be understood about any one of us. Yet in cutting off a hand or foot or in plucking out an eye, it is clear that family relations or unbelieving ministers and leaders of the church are signified.And so by "hand" we understand that priests are signified; like a hand their work in every area is necessary to the body of the church, about whom we find it written in the Song of Solomon: "his arms"—that is, the body of the church—"are rounded gold set with jewels." By "foot" we recognize that deacons are signified. In busying themselves with the sacred mysteries of the church they serve the body like feet, about which it is written in the same Song of Solomon: "His legs are alabaster columns, set upon bases of gold." And so, if hands or feet of this sort, that is, any priest or deacon, either through heretical faith or through depraved living, has become a stumbling block to the church, the Lord orders that such a man be plucked from the body of the church and thrown out. The example of his life and heretical doctrine endangers all the body of the church, that is, the whole people, when it follows or imitates such doctrine.

If somebody, in the whole body of the congregations of the church, is industrious and handy for practical action and he changes and his hand causes him to sin, the eye should say to this hand, "I have no need of you." And after it has said it, let him cut it off and throw it from him. All will still be well if his head is still blessed and his feet worthy of his blessed head, so that the head, doing its duty, may not be able to say to the feet, "I have no need of you." But if some foot is found which is a temptation to sin for the whole body, the head should say to this foot, "I have no need of you," and should cut it off and throw it away from him. It is far better for the rest of the body to go on into life lacking the foot or hand that offers temptation to sin than for the whole body to be exposed to temptation and to be sent into eternal fire with two whole feet or hands. Likewise it is good if what could be the eye of the whole body shows itself worthy of Christ and of the whole body. But if at some time it happens that this eye so changes that it becomes a temptation to sin for the whole body, it will be better for it to be ripped out and thrown from the whole body … than for the whole body together with the soul to be condemned.
