Ah, yes. Some pigs are more equal than other pigs.
Your contradictions disprove your theory. Christ either indwells a man or He doesn't. There is nothing in Scripture that says Christ indwells one of His sheep 20% every other Tuesday and 40% every Saturday, excluding bank holidays and Canadian Labor Day...
That's just more of Rome's contrivance to fill the gap between the Bible and its manifold doctrines of men.
The division of days into workday and holidays is not in the scripture? How about Christ prior to His incarnation, then during His ministry on Earth, then after, with us and at the right hand of the Father, -- is that in any scripture?
A minor point, "indwelling" typically refers to the Holy Ghost. Christ is "present" or "abiding".
