For them, the church's primary objective, as commanded by Jesus Christ, is to propagate the gospel unto all nations until the consummation of the ages, convert sinners to believe and glorify God and to make them qualify for the eternal life in heaven.
They believe in God the Father, Jesus Christ the Son, and the Holy Spirit but they adopt a nontrinitarianism orientation, rejecting the Trinitarian concept that there is "one God in three co-equal persons", which for them is against the Bible.
They believe that the Father is greater than all, greater than Jesus Christ as declared by Christ himself.
They believe that Gentile nations, including the Philippines, are partakers of the promise of eternal life, through belief in Jesus Christ and the gospel and are not authorized by God to establish their own church, but mere members associated with the same "body" or the church written in the gospel by accepting it and executing the doctrines written by the apostles.
Guided by this scriptural principle, the church's registered name contains descriptive words "ang mga kaanib" in Tagalog or "members" in English to emphasize the group's association today, as "members" of the "Church of God" that is already established long time ago and was written in the Bible.
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.
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.The Members Church of God International in the Philippines rooted from a similar denomination, the Iglesia ng Dios kay Kristo Hesus, Haligi at Suhay ng Katotohanan (Church of God in Christ Jesus, Pillar and Support of the Truth) which was first led by Brother Nicolas Antiporda Perez in Pulilan, Bulacan, Philippines in 1928.Members Church of God International, abbreviated as MCGI, is an international Christian religious organization with headquarters in the Philippines.It started as a small group with less than a hundred believers in 1977.It is popularly known in the Philippines as Ang Dating Daan (English: The Old Path; abbreviated as ADD), the title of its flagship radio and television program and currently the longest-running religious program in the Philippines with Brother Eliseo Soriano as its "Overall Servant" (Former title: "Presiding Minister").Members Church of God International believes that the Almighty God, the Father sent his begotten Son, Jesus Christ, instrumental in the establishment of the "Church of God", first planted in Jerusalem and preached by the apostles.
