And it is revealing that some who do not believe in contending about doctrine will contend for their doctrine that one should not contend about doctrine.
It is also revealing that some who do not believe in contending about doctrine will not contend for their doctrine that one should not contend about doctrine, thus indicating that they have not real sustaining basis for it.
Sound doctrine is important but it’s not supremely important. As I noted in a previous post, what is of supreme importance is loving others. We know this is true because that is the metric by which Jesus will eternally divide the saved from the lost. He does not say, in the latter half of Matthew 25, ‘You earnestly contended for sound doctrine—enter into your eternal reward.’
Neither does Jesus say, ‘You failed to earnestly contend for sound doctrine—depart from me, accursed ones, into the eternal fire.’
Rather, the metric is those who actively showed love, ‘to the least among us,’ vs those who turned a blind eye toward people in need.
When we stand before Jesus to hear our eternal fate, it will come down to whether our earthly priorities aligned with His or not. Jesus’ greatest priority is not arguing doctrine. It is just as He revealed in Matthew 25: caring for people in need.
It's like the argument that there is no such thing as "absolute truth". If someone declares this, then they are claiming what they say is absolutely true and if it cannot be (since, according to them, there IS no such thing), then there is no sense arguing about it.
