Just remember, anytime you pick up the Bible and preach, you're putting yourself out there for Gods judgement. Are you an authority on sacred scripture? I certainly can show you that you teach opposite of what the Apostles taught. Especially on things like the Eucharist. Does that bother you at all? Or does your arrogance cloud your belief and you actually think you've found some secret missing article of faith from Jesus Christ that wasn't revealed until your amateur hands got a hold of sacred scripture??
Yes we all have that authority to decide scripture for ourselves. We can then divide the word or preach to others, or author Bible commentary. If others accept it or correct us is up to them as the holy Spirit leads us all, not the man in Rome. Jesus sent the Holy Spirit to us all.
John 14:16 And I [Jesus] will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
14:17 Even the Spirit of truth; whom the world cannot receive, because it sees him not, neither knows him: but you know him; for he dwells with you, and shall be in you.
14:18 I will not leave you comfortless: I will come to you.
14:26 But the Comforter, which is the Holy Ghost, whom the Father will send in my name, he shall teach you all things, and bring all things to your remembrance, whatever I have said to you.
15:26 But when the Comforter is come, whom I will send to you from the Father, even the Spirit of truth, which proceeds from the Father, he shall testify of me:
16:7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come to you; but if I depart, I will send him to you.
16:8 And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:
