Many Churches teach that tithing is still mandatory. The Southern Baptist churches: we read in The Baptist Faith and Message (1963) the following statement: ‘God is the source of all blessings, temporal and spiritual; all that we have and are we owe to Him.hough some people believe tithing was an Old Testament practice not intended for New Testament Christians, the Assemblies of God believes and teaches that tithing is still God’s design for supporting the ministry and reaching the world with the gospel.
