Bishop Agathonikos of Arusha and Central Tanzania, as the vicar of the Diocese of Bukoba, performed a memorial service at the tomb of the blessed Fr. Sosthenes Kiyonga.
Fr. Sosthenes was the first Orthodox priest to be ordained in Tanzania with a huge missionary work.
His children are Fr. Anastasios Kiyonga, who was recently ordained a priest by the Bishop and Parthenios who serves at the Missionary Center of Iringa. They both serve near Bishop Agathonikos in the Holy Diocese of Arusha and Central Tanzania.
