In 1963, Caffiaux travelled from France to Wisconsin to become a member of the Strangite church.
[1] On his return flight to France, Caffiaux reported receiving a revelation from God that he was the rightful successor to Joseph Smith, Jr. and James J. Strang and that he should become the head of the church.
[1][2] In 1964, while visiting Iran, Caffiaux reported being visited by an angel in a vision and being ordained a prophet, seer, and revelator and the embodiment of the First Presidency of the Melchizedek priesthood.
At a conference of the Strangite church in France, the Strangite adherents voted to rename their congregation "Église sainte de Jésus Christ" — the "Holy Church of Jesus Christ".
[1] In 1966, the Holy Church of Jesus Christ had congregations in France and in New Mexico in the United States.
