Mr. Salza seems like a nice enough fellow - however, having done some homework in this area I know that Salza makes some inaccurate statements about historical Christianity - for example - "sola scriptura" was not invented by Martin Luther in the 16th century. Many of the "Church Fathers" that Rome looks to that lived way back - some knowing the Apostles - would never allow any doctrines that were contrary to or not found in the Scriptures. He also uses circular arguments - he believes the RCC is "fullness of truth" because the RCC says it is. The RCC says it is infallible in all matters of faith & morals therefore it must be true. Nice try Mr. Salza - I suggest all to be like the Bereans and check to see if these things be so...
