No, they do not have the liberty to interpret scripture as it seems right to them. They have a responsibility to God to honestly appraise the scriptures as they are written and follow the commandments God has given us. We don't fashion the scriptures to suit our desires. We conform to what is written.
If they do not approach the word with fear and trembling to do what is right in God's eyes, then I would suggest they're probably not even Christians in the first place.
Now, can you honestly say that the Church has never taken advantage of the scriptures for their own gain?
We limit ours to Scriture. They claim to have Scripture on the same level as the Magesterium, but they seem to always default to their interpretion of the latter.
Give me Scripture. If is far less convulated than the tradition of men..
One would be hard pressed to find some that DIDN'T on both sides of the theological fence.
