We should not pay for anything whatsoever in the course of preaching the gospel. The gospel is to be preached freely without any payments whatsoever. The Lord Jesus Christ brought the gospel to us freely. He paid for it with His own blood. We are not going to pay for the gospel.
The doctrines of making contributions in the church is not a commandment it is a free will action. We have learnt that there are actions in the church which we are going to do not as a commandment but as a voluntary action. It is a free willed action. The giving of contributions is what we do out of our free will. We should not be forced to pay any compelling contribution for the course of the gospel.
Tithing was a commandment in the old testament. In the new testament it is not a commandment. The Lord Jesus Christ did not command his disciples to pay tithes. So, we should not force people to pay tithes. Whatsoever anyone wants to give to the work of the gospel should be done without being enforced.
