One reasons that the tithe may be applied to school purposes. Still others reason that canvassers and colporteurs should be supported from the tithe. But a great mistake is made when the tithe is drawn from the object for which it is to be used—the support of the ministers.... CS 102.3
The tithe is the Lord's, and those who meddle with it will be punished with the loss of their heavenly treasure unless they repent. Let the work no longer be hedged up because the tithe has been diverted into various channels other than the one to which the Lord has said it should go. Provision is to be made for these other lines of work. They are to be sustained, but not from the tithe. God has not changed; the tithe is still to be used for the support of the ministry.—Testimonies for the Church 9:247-250. CS 102.4
