In 1989, John Tangalobani from Ambae, a School Teacher, a Unionists who was at the forefront fighting for Teachers rights,once a soccer player at the Teachers College as a student with some experience in Renewal Movement pledged his allegiance to become the first United Pentecostal Church Pastor of Port Vila after being converted to the Oneness Truth. The doctrine of the Oneness Truth and the true way of salvation in Jesus Name was never known until the coming of two missionaries from the States to Vanuatu back in 1983 that ended up baptizing a Tongan born Ni-van in Jesus name, Brother Funa followed by Late Pastor James Kalmet in 1984 during their second visit. It was through Late Pastor James Kalmet, initially a Holiness Fellowship Pastor who started a family gathering at his home at Pango that eventually led to the establishment of the Pango Pentecostal Church where John Tangalobani and his wife, Katiri Tangalobani were members then.

Known at the time by Trinitarians as JESUS ONLY church, John Tangalobani was joined by his wife who was also a school teacher, teaching at Pango Primary School when they received a call from God and the blessing from the Pango Pentecostal Church to move and started the Pentecostal Church of Port Vila, which we know today as Apostolic Christian Tabernacle (ACT). Besides John Tangalobani as the Senior Pastor, Harry Kalo from Makira Island, a Musician who loved country music, played string band in his youth, practically a carpenter/builder all his life was appointed Assistant Pastor to the newly Port Vila Pentecostal Church.

  At that time, the doctrines and the beliefs of the United Pentecostal Church International of Vanuatu (UPCIV) was in its infant stage. This meant a lot of preaching and teaching were required by Pastor Tangalobani and his Assistant Harry Kalo to instill the Oneness Truth doctrine and the true salvation message based on Deuteronomy 6:4 and Acts 2:38 to the hearts and minds of those who have been taught previously the trinity doctrine given that the Port Vila Pentecostal church was the only one besides the Late Kalmet’s Pango Pentecostal Church. As the need and demand for the Oneness truth message increased, the Assistant Pastor was used by the Senior Pastor as the evangelist of the local church to boost Oneness truth and baptism in Jesus name message to the wider community within Port Vila and through the islands of Vanuatu.

 With a new role coupled with the new Oneness doctrine and true salvation in Jesus Name belief, Pastor Tangalobani and his Assistant at the time may not have fully visualize where they will end up and in which direction God will lead them just like Abraham who by faith went without knowing where he was going when God called him. While they may not have the full vision at the time of having a permanent Church Land and Church Building, their newly Pastoral roles to assume could just meant a Ministry work with temporary shelters good enough for the few saints at the time.
