The bible as well as the Holy Spirit is what will lead mankind in to all truth. (John 16:13) The Spirit will NEVER contradict the Word of God. The problem with denominations is that people only accept what they have personally experienced or what they want to obey. Many have decided that if they have not received what the bible depicts as necessary, such as the Holy Ghost with the evidence of speaking in tongues, then there personal experience trumps God's word. They profess to be right regardless of what is clearly expressed in God's word. WRONG!
The ONE and only common salvation can be found by earnestly searching out what was delivered to the saints/disciples as recorded in the word itself:
"Beloved, when I gave all diligence to write unto you of the common salvation, it was needful for me to write unto you, and exhort you that ye should earnestly contend for the faith which was once delivered unto the saints."
Jesus declared that the repentance and remission of sin would be preached in ALL NATIONS and would begin in Jerusalem. (Luke 24:47) What event directly parallels Jesus' words:
Beginning in Jerusalem on the Day of Pentecost, Peter told those present that they had crucified their messiah, Jesus. Upon believing Peter's words they asked what was required of them. Hear his words, "Repent, and be baptized EVERYONE of you in the name of the Lord Jesus FOR the remission of sin, and you shall receive the gift of the Holy Ghost. He went on to say that the promise of receiving the Holy Ghost upon obedience was for AS MANY AS THEY LORD SHALL CALL. The message started in Jerusalem would be carried by disciples into ALL NATIONS. This is going on even unto today.
Many ascribe to the words of "church fathers," etc. Relying upon personal interpretations of human beings no different than you and I is foolish. If their understanding does not comply with the actual written word it is useless in determining truth.
