His Grace Bishop Agathonikos of Arusha and Central Tanzania, exercising his duties as locum tenens of the Bukoba Diocese, conducted a Trisagion service on the tomb of the late Fr. Sosthenes Kiyonga. Fr. Sosthenes was the first Orthodox priest ordained in Tanzania with a huge missionary work. He is the father of Fr. Anastasios Kiyonga, who was recently ordained as a priest by his Grace Bishop Agathonikos, and Parthenos, who serves at the Mission Center of Iringa. Both of them serve near his Grace Bishop Agathonikos at the Holy Diocese of Arusha and Central Tanzania.
