I heard in church, years ago. The "eye of the needle" is a

Have to unload all the cargo off the camel, which camel then
has to crawl on its knees through the low opening. Cuts down
on armed invaders, or slows em down a bit.

Yep. That idea has some merit.

For example, at the Church of the Nativity in Bethlehem, a 12-foot tall main
entrance was, in antiquity, mostly blocked off so that only people afoot
could enter. This was done, according to a guide, because marauders once
rode their horses into the Church.

But the camel business is a rationalization for something otherwise foolish.
The "rope" idea makes more sense.
