To me, it has become abundantly clear, that the use of Malachi 3 to teach and propel a message of Tithing into the New Testament church is a misappropriation of Scripture. While Paul taught clearly in II Corinthians 9:6-7 that God loves a cheerful giver, and that our reaping will be commensurate with our sowing, he equally taught that our giving was no longer obligatory (tax, tithe) and that we were to give as we felt led to in our heart.
Oneness Pentecostalism (Apostolic, or United Pentecostal Church International) is known for legalism, rules and regulations. Strict dress codes, women can’t cut their hair, wear paints, make up, dye their hair. But all of that aside, there are some other striking similarities to Midieval Catholicism that might shock you.
