Turang was born in Tataaran, Minahasa Regency in North Sulawesi.

On 27 July 1997 Turang was ordained bishop by Cardinal Julius Darmaatmadja.

Turang officially succeeded Manteiro at the latter's death on 10 October 1997.

[1] Turang caused some controversy in the Indonesian Catholic community when he reprimanded a priest named Romo Yohanes Subani.

Subani who is an educator and instructor at St. Michael High Seminary in Kupang, did not kiss the bishop's ring on January 10, 2013 after a joint Christmas celebration at Kupang Cathedral Church, causing Turang to publicly admonish Subani in front of the congregation.
