REALLY??
There are OODLES of historical evidence.
Let's start with Ignatius of Antioch, who was a student of John, the Apostle. He wrote 7 letters to 7 Church communitees on his way to be martyred in AD 107. Here is an excerpt from the Letter to the Smyrnaeans:
Ignatius of Antioch
The sole Eucharist you should consider valid is one that is celebrated by the bishop himself, or by some person authorized by him. Where the bishop is to be seen, there let all his people be; just as, wherever Jesus Christ is present, there is the Catholic Church (Letter to the Smyrneans 8:2 [A.D. 107]).
A few dacades later, Irenaeus wrote:
The Catholic Church possesses one and the same faith throughout the whole world, as we have already said (Against Heresies 1:10 [A.D. 189]).
Oops - almost forgot about Acts 9:31.
Acts 9:31 talks about how the Early Church grew throughout the region. The language used here describes the Catholic Church:
“Then the church throughout Judea, Galilee, and Samaria experienced peace and thus was strengthened. Living in the fear of the Lord and in the encouragement of the Holy Spirit, the church increased in numbers.”
According to Strong’s Greek Concordance and Lexicon – which is used by Protestants AND Catholics alike – the verse is translated as:
“The true Church throughout all Judea . . .”
Here is the phrase in Greek:
η μεν ουν εκκλησια καθ ολης της ιουδαιας
The Catholic Church gets its name from the GREEK for “according to the whole” and “universal” - εκκλησια καθ ολης, which is pronounced “katah-holos”.
Εκκλησια (ekklesia) - A gathering of citizens called out from their homes into some public place, an assembly; CHURCH
καθ (katah) - Through out, according to
ολης (holos) - All, whole, completely
"Kata-holos" = CATHOLIC.
Sorry to kick the chair out from underneath you but you're WRONG.
