While at Sagegi in 1958, serving as a Catholic catechist, and living in the home of another catechist known as Petrus Pitalis Ogeka, Simeo Ondeto is said to have died for 3 days and came back to life with a mission-focused approach. After rising from death, Ondetto began to call himself the son of God. He was now preaching that he had gone to confer with God the Father about his mission and was freed to begin his mission. He describes a visit to heaven, chats with saints, angels, and God. Simeo Ondetto permitted the baptism of polygamists and the baptism of old Catholic converts without going through catechism training. He also said that he was sent to start a church called Legio Maria.
