Where does it mention Catholic?
People can not just get together and add to what He has revealed.
But this is exactly what you have done, and this was the Protestant ‘reformation’ – breaking away after 1,500 years from the Church Christ established.
Paul warned us about those introducing false teachings, "For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear. They will turn their ears away from the truth and turn aside to myths." (2 Tim. 4:3–4).
There was only “The Church” until the heresy of the Reformation.
The protestant “reformation” is simply not Biblical:
“I appeal to you, brothers, in the name of our Lord Jesus Christ, that all of you agree with one another so that there may be no divisions among you and that you may be perfectly united in mind and thought. My brothers, some from Chloe's household have informed me that there are quarrels among you. What I mean is this: One of you says, "I follow Paul"; another, "I follow Apollos"; another, "I follow Cephas"; still another, "I follow Christ."
Is Christ divided? Was Paul crucified for you? Were you baptized into the name of Paul? I am thankful that I did not baptize any of you except Crispus and Gaius, so no one can say that you were baptized into my name. (Yes, I also baptized the household of Stephanas; beyond that, I don't remember if I baptized anyone else.) For Christ did not send me to baptize, but to preach the gospel—not with words of human wisdom, lest the cross of Christ be emptied of its power. 1Cor 1:10-17
You could easily read the above as “One of you says, "I follow Luther"; another, "I follow Calvin"; another, "I follow Wesley"; still another, "I follow Christ."
Christians cannot be “perfectly united in mind and thought” when they have different beliefs on, say, the necessity of water baptism, while others believe “This is my Body” means “This is a cookie”
There can be only one ‘Truth’ – Christ is THE way, THE truth, THE life. One, not many.
And what if you have a disagreement with a brother as to what is ‘The Truth?’ Where do you go to resolve your issue? Scripture tells us what to do:
"If your brother sins against you, go and show him his fault, just between the two of you. If he listens to you, you have won your brother over. But if he will not listen, take one or two others along, so that 'every matter may be established by the testimony of two or three witnesses.' If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, treat him as you would a pagan or a tax collector.
Right – the Church.
“But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and foundation of the truth.” 1Tim 3:15
