" But the authority to interpret God's word doesn't rest with an individual or group. It rests with Christ alone -- all authority is His (Matt. 28:18) as the book is all about Him (Lk. 24:27). And while Christ gives teachers the ability to interpret and teach (Neh. 8:8; 1 Cor. 12:28), or councils wisdom to discern (Matt. 18:15-18), His authority is found in the text alone, and those who interpret it correctly (2 Tim. 2:15). His people will hear the correct interpretation, because the Holy Spirit will guide them into all the truth (Jn. 16:13; 1 Jn. 2:20)."
Baptism is baptism, so long as you believe. It doesn't matter if Judas baptized me. There is no record of anyone baptized that had to be baptized again; it is for believers, and if the pastor proves false, it DOESN'T mean that my baptism, if I believed, was false too.
