It is true, along with the regeneration of heart we are called to continually renew our minds (Romans 12:2). However, this renewing of the mind found in this passage is in relation to our orthopraxis (right action).
I say this because of the schism we have over disagreements in orthodoxy (1 Corinthians 12:25). We disagree on a certain aspect of theology and then challenge the saving work of the Lord in that person's life.
Taking a cue from the book of James, it appears orthodoxy should serve orthopraxy.
But someone will say, "You have faith; I have deeds." Show me your faith without deeds, and I will show you my faith by what I do.For your consideration: If salvation was determined by orthodoxy, than it's precarious that new converts are in the faith until after a thorough schooling on all doctrines and they adhere to them all 100%.
You believe that there is one God. Good! Even the demons believe that—and shudder.
You foolish man, do you want evidence that faith without deeds is useless?
This isn't to discount orthodoxy, I feel it is quite important to learn and teach correct doctrine. I feel doctrine is important in so far as it affects works lived out. For example: some dispensationalists believe the church is not called to feed the hungry or care for the widows and orphans because these deeds are left to those not caught up in the so-called rapture. I find this a dangerous doctrine because it impedes good works, and ignores much of scripture. However, we can engage these doctrines without splitting the Body of Christ into warring factions.
So let us engage one another with love, looking out for the interests of others before our own, being humble in all we do so that love may be found, and peace may abound.
