No, it really does matter. Yours is a man-made answer to deal with your man-made church.
Look at Scripture - How do you make sense of the following?
"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. "I tell you the truth, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven. Mat 81:15-18
So where is the church? Where do you take your concerns? This makes no sense whatsoever without the visible Church Christ established with teaching authority, and the power to loose and bind.
Think about it. Would Christ establish his Church to teach the way, the truth and allow thousands of interpretation as to what is the truth? If the Church doesnt teach the Truth, Christ is a liar. If He would allow multiple versions of Truth, hed be an idiot. I dont believe He is either.
So what leads you to believe that the RC church is still the true church? The definition of " the church" is the body of believers that believes God's Word (the Bible) to be the truth . You say that you believe Gods Word and I have no reason to think that is not so, I believe that same Word to be true. We are both members of the body of Christ, the Church.
What does not matter is petty arguments over it. They will not change the fact that the "Church" is all of the body of believers in Jesus Christ and Gods Word on the subject. You can point out all the arguments you want about the details, and I and other true Christians will say to you that we agree with anything that is stated in the scriptures, the Bible, but have a good reason to doubt that which is not stated in the Bible, as explained in my previous post.
No where in scripture nor in that verse is the word church used as it is conceptualized by the Catholic Church. The word used is ecclesia which means an assembly of those called out. They were to take it to the assembly they worshiped with, not to some corrupted conglomerate that has become the Catholic Church. Catholics start with a corrupted term "church" and build many corrupted concepts that are totally against what scripture teaches.
