They fiercely fight to keep those chains of bondage. And they have read the Truth here over and over and it has no effect. The lies/deception they were fed have taken deep roots. They have no one to blame when the time comes. Time is better spent on those who want to hear/learn The Truth, IMO.
Sadly, 2 Cor. is completely ignored. "Wherefore henceforth know we no man after the flesh: yea, though we have known Christ after the flesh, yet now henceforth know we him no more." 5:16.
Once He ascended into heaven, everything became spiritual. Our baptism into His body, our conversation, our promises, our blessings, our position in Him.
The flesh profits nothing. Except deceit. We are told to put no confidence in the flesh. Those 5 senses that have led more men astray than we could possible imagine.
"For ye see your calling, brethren, how that not many wise men after the flesh, not many mighty, not many noble, are called. ...That no flesh should glory in his presence." 1 Cor. 1:26-29.
They not only glory in his presence, they believe that they can consume His glory in their bodies at mass. Completely OPPOSITE of God's Word. Not just not close, but diametrically opposed.
Don't kid yourself. If you do-it-yourself theologians could give true freedom...I'd still be one of you.
