There is something I don't understand in your comment. You said a person should not take anyone's word as authoritative, and yet you imply that you take your own word as authoritative. Why is your word authoritative for yourself?
On the other hand, I know what I think and why I think it. I can test the logic and soundness of my own reasoning and that of others, but I cannot know what their biases are as I do my own.
At some point you have to make a choice as to what is right, at least as far as you can determine. I prefer to do that for myself rather than on the authority of anyone else, even God.
The fact that I agree, in general, with the theology of the Baptist church that I attend does not mean that I accept the pastor's authority in all things theological. As he is a seminary trained professional, naturally I treat his opinions with respect, but accept them only if I have verified his thoughts in my own mind.
He doesn't answer to God for me, nor I for him. I have to make up my own mind.
