In my 'witnessing', as just an unworthy servant of CHRIST, able to 'testify' what i have learn and 'know them by their fruit', is that, 'Religiously' the Protestant stand out mostly towards Biblical by slightly mixing and matching the Old and the New Covenant/Testament in service. The other more towards 'a cult'.
In 'witnessing' the Gospel the Protestant are clever preachers, but are poor teacher to continue the 'complete' Word/Teaching of CHRIST to those who have come in and in charitable deeds they give 'sparingly'. But the other draw people by their living examples and religiousness and vast charities.
In character and behavior of believers, both are becoming equally similar, especially the 'mainline' Protestant and those who have separated from them, churches.
i pray GOD the FATHER of our LORD JESUS CHRIST help you all to 'turn back' from 'self' deceptions of the flesh's passions and desires, that has 'adulterated' GOD's Biblical in context sound doctrine Covenant Christianity.
Those who 'practice' and 'abide' and 'bear much fruit' and 'their fruit also abide' according to the 'context spiritual knowledge' of the New and Old Covenant/testament accordingly, able to 'know all of them by their fruit'.
No need to waste time in excuses and defense of what has turned to bad fruit, in order to 'make up' to seem right. But rather 'repent'.
As it is written;
"HE has no favorites (among men)."
'HE has no regards to men."
