I have been told they are a pentacostal church, but I don't know much more than this. Not a sect, it sounds like they broke from the Apostolic Church over some bit of doctrine. I would suggest you attend a local congregation to get a feel for their brand of worship. Congregations vary, even within the same denomination. A local Apostolic Church could probably be informative, especially if the other is a breakaway subset of theirs. A pastor would know best. Ask for a copy of their mission statement, or check online for such a statement. There is bound to be direct info available, this is not an "under the back porch" cult.

"The New Apostolic Church (NAC) is a chiliastic church, existing since 1879 in Germany and since 1897 in the Netherlands. It came forth from the Hamburg schism in 1863 in the Catholic Apostolic Church, which was founded in 1847 in England and started in the 1830s as a renewal movement in, among others, the Anglican Church and Church of Scotland." "The New Apostolic Church is established in almost all the countries on this earth. Around the globe there are more than 11 million members from all age groups and areas of society." "Controversy: On Christmas Day 1951, during service in Giessen Germany, Chief Apostle J.G. Bischoff declared his "Botschaft" ("message"), announcing that the Lord had made known to him that he would not die before the Second Coming of Jesus Christ, during which the chosen people were to be taken into His kingdom (the First Resurrection). In 1954 this teaching became the church's official dogma. Those ministers, especially the apostles, who did not preach this message lost their positions and were excommunicated from the New Apostolic Church. Approximately one out of four apostles active during this time resigned or retired early, several schisming to form their own denomination. The most important "victim" of this policy was Peter Kuhlen, who had been ordained in 1948 as the successor to J.G. Bischoff. Interestingly, the impact of this message varied regionally: all of the Apostles active in South Africa resigned or retired (1954), both Apostles in South America resigned (1957), several apostles in Europe (1954-55) resigned, however, no schism formed in North America. When Chief Apostle Bischoff died on July 7, 1960, his dogma about Christ's return had not been fulfilled. In the service on July 10, 1960, Walter Schmidt was introduced as the new Chief Apostle, and during that service, the admonition to the members was to answer external critics with silence regarding the Bischoff Prophecy. The New Apostolic Church continues to maintain that it was a valid Godly message. The excommunicated ministers and members were not reinstated, up to the present day. The French Commission on Cults registered the New Apostolic Church as a cult in 1995 and 1999 reports (see Groups referred to as cults in government documents). In 1997, the Belgian parliamentary commission established a list of 189 movements containing the New Apostolic Church."

Dear friend, please read the "self image" of the New Apostolic Church to get a feeling about their belief. Here is the link: http://www.nak.org/en/about-the-nac/self-image/ The belief of the NAC is similar to the Roman Catholic Church with similar dogma like them. They believe that their apostles are necessary to get the holy spirit and to get forgiveness of sin. In the last 1-2 years they became more and more critical against the bible. Regards from Germany.
