As part of this later work, Balderas began assisting Antoine R. Ivins in translating the Doctrine and Covenants into Spanish in 1934.
Rhea was the daughter of Milton H. Ross, a teacher of penmanship at LDS High School in Salt Lake City.
[3] Rhea first met Balderas when he was at work in a lumber yard, dirty from his tough manual labor, and wondered if this man covered with sweat was the great missionary she had heard of, but later on hearing him speak in church meetings she fully knew it was true.
He continued working in the lumber yard and as a part-time translator for the Mexican American Mission.
In 1939, Balderas took a job as a full-time translator for the church and moved to Salt Lake City.
[4] He also worked on the first translation of the temple endowment ceremony into a language other than English, specifically Spanish, in cooperation with Ivins.
[5] In 1961, Balderas helped Marion G. Romney improve his abilities in Spanish so he could more effectively function as the area supervisor for the church in Mexico.
[8] Balderas also wrote "A Brief History of the Mexican Mission, 1874-1936" which was published in the Spanish Liahona in August 1956.
[3] He served as an officiator in the Mesa Arizona Temple as well, helping there during excursions of Spanish-speaking Latter-day Saints.
