I can’t speak for Lutherans and Anglicans and certainly not the Orthodox. However, based on God’s Word I believe they are wrong as well.
The Bible says: “Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it.” (Matthew 7:14)
Any belief shared by ALL or a majority of religionists should be carefully examined in light of the Word. The Enemy is a deceiver and the father of lies. He often works through subtle deception in the arena of religion. We should never seek affirmation of our beliefs from a group. We should be Bereans (Acts 17) and work to verify that what we have been taught is so.
As for you doubting what I know...1 Corinthians 4:3
“I can’t speak for Lutherans and Anglicans and certainly not the Orthodox. However, based on God’s Word I believe they are wrong as well.”
Okay, so many of the world’s oldest Christian groups have always been wrong you’re saying? And this is really not based on God’s Word so much as your own opinion of God’s Word, correct? After all, so many stand against you and they probably know the Bible far better than you probably ever will. In any case, what we see is that Protestants - preaching sola scriptura - still can’t agree on even the most basic of teachings. And in the end, clearly, sola scriptura is nothing but Protestant opinions on God’s Word rather than what God’s Word really says.
