Romildo Ribeiro Soares had worked with bishop Edir Macedo of the Universal Church of the Kingdom of God, but they broke off relations in 1978, after disagreements in theology. In 1980, Soares founded the International Grace of God Church, at Rua Lauro Neiva in the city of Rio de Janeiro.^[1]

The Church's first temple opened in the city of Duque de Caxias, Rio de Janeiro, followed by others throughout Brazil and in other countries.

The International Church of God's Grace is accepted and recognized as a "Legitimate Christian Fellowship Church" by other denominations and their respective ministers.^{[citation needed]}
