If something is insightful, useful, practical, truthful, helpful toward enhancing someone's personal insights and growth toward and in the Lord . . .
I think it's fitting to share virtually wherever there may be hearing hearts.
I don't pretend that those who openly contend with me necessarily fit the fertile ground for such usefulness but there are persistent occasions when lurkers assure me that such is the case.
And, Holy Spirit within me bears some witness as well.
Psychology is merely the study of organisms and behavior. When it gets to religion and humans . . . there's a lot to study.
All kinds of things can be said. All kinds of inferences can be drawn.
But, GOD ALONE is still the confirmer of all that's true vs all that's false. Everyone is always encouraged to take any and everything I say to The Lord for confirmation or trashing.
Why should psychology be banished from usefulness in religion forums?
I'd be more specific that that: Attributing psychological motives or causes for another's religious views, values or theology.
A) Irrelevant - as to theology and exegesis in particular.
B) Slippery slope to reducing all religion to psychology - the atheist's toolbox
C) When well done rides very close to ad hominin, most often crosses over into 'you're nuts'
D) Non-rebuttable, non-discussion of theology; degrades into a psychological debate
E) Review your post I truncated; imagine someone doing the same using Calvinism.
