All that is need is proof that the present Catholic Church is the same as that established by Jesus Christ. This is an historical fact. No Protestant church, visible or invisible, can make this claim.
You asserted: “... the present Catholic Church is the same as that established by Jesus Christ. This is an historical fact.” THIS is a lie, a lie so heinous that it has established a religion made to look like Christianity but is fact a paganized copy. HISTORY records the paganism inveigling which has created the catholiciism you defend so arduously.
The Catholic church cannot make that claim either.
It bears zero resemblance to the church in the book of Acts.
