Who told you that lie?
Romans 8:9 But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
Are you saying you are none of His?
Ephesians 1:13 And you also were included in Christ when you heard the message of truth, the gospel of your salvation. When you believed, you were marked in him with a seal, the promised Holy Spirit,
Have you not believed? It says "when you believed". It says "when you believed" not when they laid hands on you.
>>If you don’t keep the unwritten traditions, your faith is not biblical.<<
What unwritten traditions were the apostles talking about? Please show documented proof.
Romans 10:14ff: But how are men to call upon him in whom they have not believed? And how are they to believe in him of whom they have never heard? And how are they to hear without a preacher? And how can men preach unless they are sent?
Who sent you?
Acts 6:6 These they set before the apostles, and they prayed and laid their hands upon them.
Who has laid his hands on you?
Acts 8:17 Then they laid their hands on them and they received the Holy Spirit. Now when Simon saw that the Spirit was given through the laying on of the apostles’ hands, he offered them money, saying, “Give me also this power, that any one on whom I lay my hands may receive the Holy Spirit.”
Acts 19:6 And when Paul had laid his hands upon them, the Holy Spirit came on them; and they spoke with tongues and prophesied.
1 Timothy 5:22 Do not be hasty in the laying on of hands.
Ephesians 1:13 And you also were included in Christ when you heard the message of truth, the gospel of your salvation.
It says “heard”, not read. Of course what they heard was “repent and be baptized, every one of you.”
The proof is that the Church teaches them. The Church, who's the pillar of truth. Your view of Church and bible is upside down. The Church authenticates Scripture because it comes from her. The Bible authenticates nothing, interprets nothing. All of that is the Church's job.
