[GonzoII]

"Protestant do not deny the Catholic church as a historical entity — so evidence of the historical basis of the sacraments, heirarchy, etc. does not seem to be germane."

It is germane if you make the link back to the apostles and therefore Christ himself, because Christ said he would be with his Church forever and it would be free from teaching error.

If you find the historical Church you find the security of God's protection over it.

Another wholly unprovable point (apostolic succession).
