Generally it's assumed in Orthodox circles (and rightly so IMO) that we need to be taught spiritual truths by others. The Ethiopian Eunuch is often held up as a good example to follow:
"And Philip ran thither to him, and heard him read the prophet Esaias, and said, Understandest thou what thou readest? And he said, How can I, except some man should guide me? And he desired Philip that he would come up and sit with him." - Acts 8:30-31
In light of this belief, though, there is one passage which confuses me:
"But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him." - 1 Jn. 2:27
What are we to make of this passage, and it's statement that with the Holy Spirit in us we "need not any man to teach [us]"?
