Your claim. Unproven. Unsubstantiated. Unsupported by evidence. Must be a Protestant thing.
The Catholic Church is THE Church. You're in sect. Your sect is puny. Most likely your sect is little known or even unknown to history. Your sect may have been founded last year or a century ago or perhaps about 470 years ago. In any case, compared to THE Church, it is just a novelty, a sect and it was founded by a man, just a man while the Church was founded by God.
