Abandon logic and common sense?
Done and done, I'd say.
The seat of Moses from Matthew 23 is a bit of a complex question for all. I’ve written and gotten responses though with some people with apologetic sites. I may take this up with them. But some of those other statements were a lot more clear to understand in the original link above http://www.thecatholictreasurechest.com/whereis.htm . We have to take care to devote too much time investigating when we should pray or read Scripture. That’s why I’ve often foregone apologetic arguments; because there isn’t much new under the sun and most of it has all been covered before though there is always more to know.
