On Division in the Church

No Christian belief can be separated from action. If it can, then it is no more than speculation. Maturity, according to Paul, is a growth in knowledge that results in right action. Hence Romans, "be transformed by the renewing of your mind, that you may be able to test and approve what God's will is..."

This is why doctrine is important. But doctrine that does not speak into our actions is nothing. Hence Romans, "the form of teaching to which you were entrusted." The imagery there is of being molded around a teaching. It is not a teaching dully possessed, to be chatted about around fireplaces, at seminars and forums, etc. It is to be lived.

To separate belief from action is dualism. But so is to separate action from belief.

What we believe about things matter. If someone teaches Biblical untruth it will eventually make its way into practice, once it has overcome the cultural stigma that went before it.

My point is that what you believe matters. The Scripture was meant to give clarity.
