In 1955, Bishop Lena Thomas answered the call of God to establish the Gates of Heaven Pentecostal Church at 4410 Lancaster Avenue; one year later, they bought a storefront at 867 Belmont Avenue and later purchased the building next door. Her husband passed away one year later. Though the building was small the work was great, she had a special way with the youth, the Saturday joy night services and all night prayer meetings drew young people from all over Philadelphia, New Jersey and Delaware.
Bishop Thomas and her young people could be found on Tuesday and Thursday nights during the summer ministering on the street corners in trouble areas of the city. Her ministry extended beyond the pulpit to the alcoholic, drug addict, the homeless and the single mother. Bishop Thomas’ ministry did not stop at 869 Belmont Avenue; the Lord led her to establish churches throughout the city, Beulah Tabernacle Pentecostal church at 49th and Baltimore Avenue, Reverend Keith Thomas, her grandson serves as pastor, he preceded her son the late Elder Calvin Thomas, Sr. The Open Mission True Light church at 52nd and Parrish Streets, under the pastorate of her granddaughter, Reverend Dr. Maureen Davis.
In December 2001, Bishop Lorraine Thomas Ware, succeeded Bishop Lena Thomas and was installed as pastor of Gates of Heaven Pentecostal Church, Inc. She faithful served and expanded the international missional efforts for 22 years until her passing in July, 2023.
