La Luz del Mundo (The Light of the World) is a Christian denomination with international headquarters in Guadalajara, Jalisco, Mexico. The church is based on a Christian doctrine centered around two charismatic leaders, Eusebio Joaquin Gonzalez, known as "Aaron the Apostle" to his followers, and since 1964, his son Samuel Joaquín Flores, known as "the Servant of God".
The founder of La luz del Mundo was Eusebio Joaquin Gonzalez. He was born in 1896 in Colotlan, Jalisco to a family of small means. In the Mexican revolution he joined the constitutionalist army and fought the rebels from 1915 to the end of the war in 1921, and stayed in the army until 1926. In 1926, while serving in Coahuila he came into contact with ministers of a Pentecostal church and left the army.
He and his wife Elisa lived in Monterrey working as servants for leaders of the church, but on the night of April 6, 1926, he claimed to experience a revelation in which God spoke to him, gave him the name Aaron and charged him with the task of restoring the primitive Christian church and establishing a new chosen people. With his wife he left Monterrey and journeyed on foot to Guadalajara, Jalisco.
At this time Jalisco was the center of the Cristero movement, a Catholic movement involved in an armed conflict with the anti-catholic administration of Plutarco Elías Calles. Gonzalez' anti-catholic stance and his relations with high standing army officials enabled him to get a good footing in Guadalajara, where he was able to recruit a substantial number of followers especially among the poor. In the early thirties he was able to purchase a large tract of land on the outskirts of Guadalajara. On this land he constructed the first church of the movement and the sold the rest in parcels to church members, effectively building an entire neighborhood of devotees which he called "La Hermosa Provincia" (the Beautiful Province). Aaron started missionary efforts in Central America and by the early sixties La Luz del Mundo had 64 congregations and 35 missions.
