Wow. Take a moment to reread what you wrote, I don’t that is what you really mean.
There’s no compulsion in religion. Where you have freedom of religion you are going to have splits, when our governments cease dictating who can believe what, this is what you have. You think it is a bad thing. I don’t. What I believe is that it frees up man to make a study and an an attempt to come to truth without any type of physical threat looming over them. I trust that whoever truly seeks God will find Him because that’s what He tells me, I’m not as concerned about the splits in Christendom in the same way you are but it grieves me just as deeply because I do think Jesus wants unity. What type and what form that would come in is where we differ.
Again, sola scriptura does not kick all tradition to the curb.
I would say that it could hinder the salvation journey if misused, misunderstood, etc… that’s why you’ll hear many protestants teaching a “better safe than sorry” approach. But, it would also depend upon which prayers are said and to whom they are directed. So, for simplicity, lets use the Our Father; as long as it didn’t amount to vain repetition for someone, then it would not hinder the salvation journey and could even help it.
There is only One Truth and it is a Person; Jesus Christ. I believe, for example, (Some) Baptists know Jesus and preach Him, (Some) Methodists know Jesus and preach Him, (Some) Roman Catholics, Orthodox, etc… God uses whatever comes into a persons life for that person’s good, if they love Him. He will guide them into wherever He sees fit for His purpose. Once I tell Him I’m His and that He can send me and I’ll go, can any of us know where we’ll end up? Labels don’t determine salvation.
What I say is just for clarification; would I think it better if an RC saw the gospel in the same manner as me? Absolutely. But my job isn’t to try to sway anyone, my job is to share the teachings that are true. I understand not everyone is going to agree with that, of course they aren’t. I’m a fan of absolute truth, but we have to remember in Christianity, absolute truth is seen as an actual Person. The way is narrow and few there be that find it, but that doesn’t give me the right to be uncharitable to people, but when I speak I’m going to speak truth, and if people disagree that is their right.
If I don’t know the answer to something I admit it; it’s like the apostasy debate on another thread. Can apostasy void salvation; I dunno yet, I see both sides (OSAS) and the predominant view of the RCC. Still working on that one. lol
This is where working out our own salvation with fear and trembling comes in. Prayer, study, scripture and the Holy Spirit is my only answer to you. I can give an example if you like; The Trinity. It is perhaps one of the hardest concepts to really grasp and understand. How do we know if the teaching that God is Triune is true and what does it mean and how can it be? I studied and read and prayed and read and studied and prayed and agonized and read an studied and meditated. Always asking God to help guide me. One day it just cleared for me after praying and thinking, and it all made sense it all fit with the pictures in scripture, it all fit with how the world works, and the descriptions of God, etc… I know it because I know it and something on that level can only be truly owned and grasped if we come to that truth by His help.
For some if a certain church or person says it, that’s good enough for them. I can’t say that’s true for me, I have to do as I preach and search scripture, study, pray, and ask God to help me understand it.
Look at Peter

Flesh and blood didn’t reveal it, but the Father in Heaven did.
Thank you for your kindness and questions!
