Little is known about Bishop Cook. In 1910, he was sent to Montclair, New Jersey, and remained in charge of a tabernacle there until it was dismantled in 1913. The following year, he was sent to Yonkers, New York where he led a different tabernacle. When America joined the World War, his tabernacle was called to return to the Church's headquarters. He sent the members who were with him to the headquarters, but he refused to go as for some unknown reason, he had become very unpopular at headquarters. He was then cut off from the leader, Chief Evangelist Malinda Dora Morris, for the following three years.

​

In his own writings, Bishop Allan expressed his thoughts and feelings concerning the Church and outside world.

 

"The white people did not turn me down, they stuck by me. My finances came directly from them. They really befriended me, and I cannot thank the God of Heaven enough for them. When my people laughed at me and rebuked me, the good white people were with me, and helped me to preach righteousness to my people. Allow me, my friend, to speak a word for the Mother Church, whose leader is Evangelist M. D. Morris, the title she holds is, the Queen of Israel. She is the chief evangelist, set up over all of the daughters who are in the Church of God and Saints of Christ. She and her ministers are the founders of this church. She is helping people who cannot help themselves. She is their spiritual mother, and she loves them. She wants me there until after the great destruction on the earth, but I have a work to do. I shall go and warn the people of the coming destruction among all nations.

When we as a people of God learn to know and control ourselves, and be guided by the words of God and His righteous spirit, then true love will come in and a true smile will cover your face, and sunshine will come out of your heart. The meanest man will feel good when he sees you and will respect you, and encourage you to keep it up."
