The Protestant’s Dilemma
If Protestantism is true, all are fallible. So the Protestant must rely on his own judgment above that of his church. And the orthodoxy of the church itself is judged against his interpretation of the Bible. Thus is becomes impossible to distinguish between what divine revelation actually is versus what a fallible human being thinks it is. This fact makes the Catholic Church, philosophically speaking, preferable to Protestantism, since God’s truth can be known—and known with certainty.
1Jn 2:27 But you have received the Holy Spirit, and He lives within you, so you don’t need anyone to teach you what is true. For the Spirit teaches you everything you need to know, and what He teaches is true—it is not a lie. So just as He has taught you, remain in fellowship with Christ.
More proof that Catholics DO NOT READ THE BIBLE.
Expressing your fallible opinion.
Sorry if the truth hurts.
Regarding the Biblical passage, I have no dispute with that message.
However, we must both realize that individual interpretation made by individuals can be false or misleading as God gave us free will to accept or reject His teaching. So the Holy Spirit can instruct our conscience, but man has his biases and is able to chose how he leads his life as moral by God's teachings or by his own interpretation.
My personal opinion is that most people need the assistance of the Catholic Church to fully understand God's Word and to achieve salvation. But even then, some do not fully accept or practice Christ's teachings.
