I study "systematic Theology" in a Reformed Church. I haven't come across any unbiblical teaching so far. I was hoping you could reveal what you found unbiblical in your experience.

Mat 13:41 - The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity;
