Why I call myself, Apostolic.
I call myself Apostolic, meaning I believe on Jesus according to the word of the Apostles of our Lord Jesus Christ, as Jesus himself prayed to His Father.
Joh 17:20 Neither pray I for these (the Apostles, the men you have given me) alone, but for them also which shall believe on me through their word;
The word, Apostolic, in itself is not entirely scriptural, though derived from the scriptural term, Apostle. John declared that the Apostles were of God and that if we did not hear them, that is the Apostles, we prove ourselves and all others who will not hear them, not to be of God.
1 John 4:6 We (the Apostles) are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.
Apostolic is yet a flawed term in this regard and I accept that flaw. Apostolic is a term misused by so many that as a label, it serves up a smorgasbord of definitions. The Catholics claim to be Apostolic by succession, though in fact no Apostle would ever preach, teach or otherwise align themselves with the paganism of the Catholic church or its Trinity. The Oneness Pentecostals declare themselves Apostolic because they obey Acts 2:38, though they reject the preaching of the Apostles concerning God’s Son. Many sects call themselves Apostolic and know nothing of what the Apostles preached.
So, when I call myself Apostolic, it is with this caveat; I am Apostolic in that I believe on the Lord Jesus Christ according to the words of the Apostles.
One more thing I must note in using the term Apostolic. If I believe on Jesus according to what the Apostles preached concerning him, then I must also do what they commanded all who heard them to do. After Peter preached “Jesus, the man approved of God, who God anointed, raised from the dead glorified, appointed Judge of the Living and the Dead, and in whose name is preached remission of sins,” Peter commanded the people to “repent, be baptized in Jesus name, and receive the gift of the Holy Spirit.”
No one who is Apostolic, and those are the only ones who are in the Kingdom of God by definition, believes anything different than what the Apostles preached and does anything different than what the Apostles commanded upon espousing that belief.
