Major dogmata are outlined in Doctrine Manual of the Witnesses of Jesus Church of God (1972), and detailed in the more than two dozen books Ahn wrote. His original publications as well as scans of his notes and extant sermons have been made available online. Ahn argued that the practice of the apostolic early church had been distorted and his restorational doctrines and practices included:
Ahn, who like most Christians believed in the Second Coming of Jesus, had predicted a Second Coming "within 10 years" in 1956.:127:339:489:90 In the tradition of Seventh-day Adventist eschatology, which had been suppressed by Kuniaki Koiso during his wartime rule of Korea, Ahn further believed to be living in the end time and that the Second Coming was imminent. As Korean Protestants earlier in the 20th century had perceived Japanese occupation by identifying symbolically with the history of Israel, Ahn through biblical exegesis in his book The Mystery of God and the Spring of the Water of Life (1980) interprets the Gospel of Matthewchapter 24 verse 32-34 to suggest that the world could come to an end in 1988, 40 years after the independence of the modern state of Israel. Ahn's original The Mystery of God and the Spring of the Water of Life is made available online; World Mission Society Church of God in their later editions of the book have deleted information pertaining to the failed prediction. Ahn in his book The Bridegroom Was a Long Time in Coming, and They All Became Drowsy and Fell Asleep (1980) in a discussion based on scriptural typology, presented his conclusion that the world would come to an end in 2012:
Since the day that the Ten Commandments was received, it took 168 days to build the tabernacle and to hold the ceremony, and as the fulfillment of this prophecy, Jesus also went into the heavenly Most Holy on the 10th day of the 7th month in 1844 which is the Day of Atonement, and since then began to build the heavenly temple for 168 days namely 168 days until the ceremony. The prophecy is to be interpreted as 1 day to 1 year (Ezekiel4:6; Numbers14:34. Therefore, adding 168 years to 1844 when Jesus entered the heavenly Most Holy, 2012 becomes the last day.

This booklet was published to prevent troublemakers who misinterpret and behave fanatically, [and] explain the errors in the books that Um Sooin published ... women like Um Sooin have caused a great problem to arise with her corrupt ideas ... The Jerusalem in Heaven is Our Mother ... Um Sooin speaks as if she is out of her mind when she claims that the New Jerusalem is herself ... they assert that Um Sooin is our mother who has come down from Heaven. ... How extremely scandalous is this? With this type of misguided delusion, she has become a false prophet and has attempted to gain power. ... The New Jerusalem which is written of in Revelation 21:1-4 ... is a spiritual building not a person. .... Nobody except someone who is not in their right state of mind can believe and follow after this. ... Because the interpretation of Um Sooin was made to match their claims, they have made these ridiculous interpretations. ...

Ahn concludes his rebuking of Um Sooin:
There is never a time when the activity of Satan is cut off in the true Church. The Apostle Paul has written as follows that the Devil will utilize women to cause confusion inside the Church: "A woman should learn in quietness and full submission. I do not permit a woman to teach or to assume authority over a man; she must be quiet. For Adam was formed first, then Eve. And Adam was not the one deceived; it was the woman who was deceived and became a sinner."[1 Timothy 2:11-14] In other words, whenever a woman makes assertions in the Church, the Church will fall under the deception of the Devil.

Ahn was buried in a public grave located in Seokgye Cemetery[k] 30 kilometres (19 mi) north of Busan. From the time of his burial in 1985, a single tombstone stood beside the grave, the epitaph reading: "The grave of the prophet Elijah Ahn Sahng-hong."[l] After the death of his wife Hwang Won-sun 23 years later on 4 September 2008, she was buried in the plot beside Ahn, and a new tombstone carrying both their names (as well as their children's on the back) replaced the 1985 stone, repeating the epitaph.
The unexpected death of Ahn gave rise to a power struggle within Witnesses of Jesus Church of God: some people in the church wanted to continue along the lines laid out by Ahn, others wanted to re-introduced the concept of a "spiritual mother" embodied in the then 41 year old woman named Zahng Gil-jah[m] (born 1943). After an extraordinary general meeting in Witnesses of Jesus Church of God on 4 March 1985 failed to reconcile the opposing fractions, a schism divided the church into two sects
One group of people in Witnesses of Jesus Church of God stayed on the premisses in Busan. Among them were Ahn's wife and their three children. This sect is today known as New Covenant Passover Church of God. Ahn's son Ahn Kwang-sup[p] (born 1954) is an elder in the church and continues to expound on his father's work. An outside observer visited the church and had this comment:
The service performed at the New Covenant Church is not much different from that of the mainstream churches. The parishioners pray in the name of 'Jesus Christ' and recite the Lord's Prayer. They sing unmodified mainstream hymns. Like the Seventh-day Adventists, they observe Saturday as the Sabbath day.

Witnesses of Ahn Sahng-hong Church of God
Another group of people in Witnesses of Jesus Church of God including the man Kim Joo-cheol[q] and the woman Zahng Gil-jah wanted to re-introduce the concept of a "spiritual mother", and on 22 March 1985 moved from Busan to Seoul. On a meeting in Seoul on 2 June 1985, they established a church called Witnesses of Ahn Sahng-hong Church of God. Two major new doctrines were codified
Zahng Gil-jah should be regarded as God the Mother, a female image of God, be titled Heavenly Mother, or simply Mother, and together with Ahn Sahng-hong be regarded as God.
A change in religious practise, as reflected in the change of name from "Witnesses of Jesus" to "Witnesses of Ahn Sahng-hong", was, that prayers were no longer conducted in the name of Jesus Christ but in the name of Christ Ahn Sahng-hong.
As a central argument to the claim that Ahn Sahng-hong should be the Second Coming of Jesus, and in turn an argument for his suggested promotion of Zahng Gil-jah to the Bride of the Lamb, is the proposision that he fulfilled a Davidic prophecy by preaching 37 years from his baptism 16 December 1948 to his death on 25 February 1985, a period which in reality was only 36 years, 2 months, and 9 days. The source for the baptismal date of 16 December 1948 performed by a Pastor Lee Myeong-deok in Incheon is however obscure, and no written record exists.:125:338:494 In 2011 a protocol from the Seventh-day Adventist Church was discovered, stating Ahn was baptised when he was 36 years old on 9 October 1954 by a Pastor Gim Seo-gyeong. The investigation by The International Korean Christian Coalition against Heresy showed, that while Pastor Gim could be confirmed, no Pastor Lee Myeong-deok was with the church in 1948, reducing the length of the ministry of Ahn from 36 years to 30 years and 4 months.
Around 1997, Witnesses of Ahn Sahng-hong Church of God had established a non-profit organization titled the Church of God World Mission Society for the purpose of registering and managing the organization's assets.

^Previously a baptismal date of 16 December 1948 performed by a Pastor Lee Myeong-deok in Incheon has been reported, but the source for this date and name is obscure, and no written record exists.:125:338:494 The published references writes that with a 1948 baptism the ministry of Ahn was c. 37 years (1948-1985),:75 which has been used in argument for him fulfilling a Davidic prophecy being the Second Coming of Jesus, the use of the honorific Christ Ansanghong, and the assertation that he ascended rather than died by the World Mission Society Church of God. The investigation by The International Korean Christian Coalition against Heresy of the protocol from the Seventh-day Adventist Church stating Ahn was baptised on 9 October 1954 by a Pastor Gim Seo-gyeong showed, that while Pastor Gim could be confirmed, no Pastor Lee Myeong-deok was with the church in 1948.
