Proving the Baptist denomination to be teaching false doctrine, which makes them a man made church.

My opponent has made some very good points, I will rebut them one by one to make my point clear. 1. The bible does not speak of only one church. It kind of depends on what you mean by this point. The bible makes references to many churches, especially in revelations. Even most of the books in the new testament, are actually letters to churches. If you are talking about churches as a whole, when God says; "the church," He doesn't mean just one church, He's referencing to all churches because technically we are all connected and united under God. 2. The bible does not show one pattern of worship. Actually, I have actually struggled a bit with my opponents point here. They say the bible only gives one way of worship, but there isn't much referencing to worship in and of itself in the verses. There are many ways to worship. Worshipping isn't just singing songs half-heartedly, it's praising and giving credit to the creator of all things. Ways of worshipping God, or really anything in general, may include; Filling your time with it. (Reading the bible, praying, spending time with God) Singing Thinking about it all of the time Or even just obeying God's rules is a way of worshipping because it shows you respect Him and you will follow His commands. 3. The word denomination is not contrary to scripture. The Baptist denomination operates under one name, God. We are one body, and we are one faith. We don't do anything opposing that 4. The bible references to instruments all the time. In 1st Corinthians, He says; "...but have not love, I am only a resounding gong or a clanging cymbal..." He also mentions people playing the harp and the flute. Nowhere does he say "Thou shalt not play musical instruments" He doesn't say that directly or indirectly. Yes, He, (God) does say to lift up your voice. The voice can be used through an instrument because some people are mute. But it's also nice when people sing because they are using something to praise God with their natural abilities, not a piece of wood played with horse hairs. (A violin [But yes, those can be played too]) 5. Once saved, always saved, is one of the most truthful things ever. When someone accepts Jesus into their heart and becomes saved, there is no way that they get unsaved. Once Jesus is in you, He stays and can provide protection and intuition against sinful actions. After you get saved, God still forgives you for your sins. If you sin after you've been saved, God doesn't say; "Oh well, they're toast. I don't even want to bother them anymore. Looks like they are going to hell." In that case, if God turned His back on everybody, we'd have no salvation, and we'd all go to hell. But God is forgiving. God is patient. God is kind. God is love. He is so patient with open arms for people to come running back to him. He waits for people to ask for His forgiveness. God is a forgiving Father. In the verses you referenced, all of those aren't pointing to people who are already saved, and He never directly says to people that they will go to hell for turning their backs on God. Instead, God was referencing to the unsaved. He was basically providing a warning in some verse contexts and in others, God was basically telling the sinners, (Who proclaimed to be saved) to buck up and get their hearts straight because if they are being bad examples, they are disobeying God and everyone around them won't be saved because they won't take the saved seriously. I think for now, I have made a lot of my points. I am very quickly running out of time due to my business this weekend, so I will rebut my opponents' last two points in the next round. To end, I will make my points; I believe the Baptist denomination is not bearing a false doctrine. They, (we) basically teach everything we know out of the bible. To criticize the Baptists, is to criticize the bible, and with that, God Himself. Baptists haven't added anything to the bible, we haven't taken anything away. For example, the Mormons. Now, I love the Mormons, I love Lindsey Stirling, who is Mormon. However, the Mormons have added things to the bible that aren't completely accurate. The Baptists have not done any of the sort. We take the bible, and teach it to others the way we believe we have interpreted it. The Bible is a very confusing piece of literature so there are always going to be flaws in everyone's interpretation. However, we do our best to stay on the same track and in context of what the bible is trying to say when we teach it to others. I believe everything I have said, and have done everything to be as respectful as possible. If I have done otherwise and come across as the opposite of respectful, please let me know and I will do my best to change it. My sources; My opponent and their sources The bible (KJV and NIV) My previous Baptist and bible teachings. *Note to my opponent: Many people claim to be Christians and claim to belong to a denomination when they haven't been to church in ages. For your information, I am not one of those people. I did say previously that I have been Baptist my whole life. But now I am adding on to that, I have gone to church almost every week for my whole life. (I only skip if I am sick or out of town) and I sometimes go to Sunday and Wednesday night services. I read my bible and study it every day. I am only letting you know so you don't doubt what I know about baptism. Thank you.
