MCGI members prefer themselves to be called and identified as plain "Christians".
MCGI is not related to the many Church of God groups that descended from the Barney Creek Meeting House revival of the late 19th century in the United States.
On April 25, 1980, in compliance with government regulations, Eliseo Soriano registered the group with the Securities and Exchange Commission (SEC) as Ang Mga Kaanib sa Iglesia ng Dios Kay Kristo Hesus, Haligi at Saligan ng Katotohan, sa Bansang Pilipinas (English: Members of the Church of God in Christ Jesus, Pillar and Ground of Truth in the Philippines).
In 2004, its registered name was changed to "Members Church of God International" (Tagalog: Mga Kaanib sa Iglesia ng Dios na Pandaigdig) in line with the church's overseas expansion.
Since the year the church was established, church workers were being sent to the nearby provinces around Manila.
The program became popular in the Philippines because of its live question and answer portion.Preaching of Biblical topic is done by the Overall Servants, either live or recorded, which is being aired in all MCGI local congregations.They also personally take time to resolve spiritual and personal problems of members every Thanksgiving gathering, during the consultation period.They believe that the Father is greater than all, greater than Jesus Christ as declared by Christ himself.They do not observe customs and traditions which they consider to have pagan origins incompatible with Christianity.
