You made mention of being guided by the Holy Spirit at times… and I believe it was in relation to when reading the Bible.
The question is: If you believe that you are being guided by the Holy Spirit, how do you know with certainty that it is specifically the Holy Spirit, and not another spirit…even one of a nefarious nature?
Its a serious question.
A good place to start would be I John 4:1-4 where John gives one test to determine if the HS or another spirit is speaking.
4:1 Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.
2 By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God;
3 and every spirit that does not confess Jesus is not from God; this is the spirit of the antichrist, of which you have heard that it is coming, and now it is already in the world.
4 You are from God, little children, and have overcome them; because greater is He who is in you than he who is in the world.
5 They are from the world; therefore they speak as from the world, and the world listens to them.
6 We are from God; he who knows God listens to us; he who is not from God does not listen to us. By this we know the spirit of truth and the spirit of error.
There are at least 2 tests here. One is a person must confess Christ as being from God and the second test is does the teaching line up with the teachings of the apostles i.e. the NT. If a teaching lines up with the teachings of the apostles then it is from God and if not it not of Christ.
This has serious implications for the many Catholic teachings that cannot be grounded as a teaching of the apostles.
