Brother duCille was commissioned by Jesus Christ as an apostle of our time and a minister of the Gospel in 1948. Throughout the course of his life, both him and his wife, Mavis, carried the Gospel of the Kingdom of Jesus Christ worldwide establishing congregations throughout the globe. They first started in the Island of Jamaica. Then in 1969 they were sent by God to the United States to warn the people of God of the destruction that was coming. They founded Sonlight Ministries International and established works throughout Europe, Africa, India, and many other countries. They traveled tirelessly through the entire world, teaching and preaching wherever the doors would open to receive the revelation that God had given to them.

Sister Mavis duCille went home to be with her Lord and Saviour on November 22, 2008.

Brother Cecil duCille went home to be with his Lord and Saviour on October 20, 2009.

They faithfully served the Lord in ministry for over 60 years. Although their passing was a great shock and loss to many of us, we rejoice in the sovereign will of Almighty God, knowing that precious in His sight is the death of his saints. We are so thankful for the many years of faithful ministry to the Lord. Both Cecil and Mavis dedicated their lives to the Body of Christ, and we have all been eternally blessed by their sacrifice. They most certainly fought a good fight, finished their course, and kept the faith. There is therefore laid up for them a crown of righteousness. They have now joined the ranks of that great cloud of witnesses. May the fruit of their labor continue to flourish in the earth until His glorious appearing.
