Another form of weak theology is found in Charismatic or Pentecostal circles. It can be described as Neo-Platonic Pietism. This theology diminishes the material world. The only valid concern for these types of Christians is inward spiritual experience. Politics to them is part of the material world and therefore evil.
Ideas have consequences.
Another very popular form of theology that has caused some unintended consequences is Arminianism. This system rejects God's sovereignty. Rejection of God's sovereignty has serious consequences. When God's sovereignty is rejected or minimized, someone or something, namely man or the state, will assert his own sovereignty. In our society a vacuum has been created which the modern state has rushed in to fill.
