Now, this insult, the “Sugar-coated Yopios”, is an example of true humor in that there is at least some truth to it - therefore there is some humor.
But, the problem is, this is also a gross simplification of all Reformation theology - that there is no accountability for teaching false doctrines from the Bible. Our accountability will always be from God Himself - which has always been the case - whether Catholic or Protestant.
Another problem with your “Yopios” joke is that the same charge can be leveled at Catholic interpretation as well. Is not the Pope a human being like all of us? Are the Cardinals also human beings as well? Aren’t you taking their word for it that what they say is from God?
Catholicism has a strong authoritarian structure when the Pope makes his pronouncements in behalf of God, but again, aren’t you taking it on faith that he is not just giving his own personal views on these pronouncements regarding Biblical doctrine and teaching? So, whether it’s just some uneducated Joe Blow who is making claim to Biblical teaching or if it is from a duly elected man to the position of Pope, it is still a matter of interpretation from an individual, or an individual organization. Both can be just as equally wrong.
There are definitely tried and true methods (hermeneutics and exegesis) to accurately interpreting the Bible - i.e. context, translation, historical setting, etc. So, you’re “Youpios” is incorrect in it’s thesis that all reformation believers are free to interpret the Bible any way they want. Most Protestant denominations DO NOT believe that. They believe that ALL believers can and should read and study the Bible, and, that ALL believers can learn to accurately interpret Scripture - but, with the understanding that others can examine their line of reasoning and whether or not they have indeed followed legitimate Biblical exegesis.
All of us fall under God’s authority - it is to HIM alone that we must give an answer for what we do and say in His Name.
