CARM is a 501(c)3, non-profit, Christian ministry dedicated to the glory of the Lord Jesus Christ and the promotion and defense of the Christian Gospel, Doctrine, and Theology. CARM analyzes religions such as Islam, Jehovah’s Witnesses, Mormonism, Roman Catholicism,Universalism, Wicca, etc., and compares them to the Bible. We also analyze secular ideas such as abortion, atheism, evolution, andrelativism. In all our analyses we use logic and evidence to defend Christianity and promote the truth of the Bible which is the inspired word of God.
Here is a great resource for sermons and also research. It provides great quotes from original sources. I have started a study on Mormonism an up coming sermon and CARM has been a very helpful resource.
