Fluent in Hebrew, Yiddish, English, French, Italian, German, Tigrinya, Oromia, Geez and Amharic languages, he introduced the Beta Israel community to the first Hebrew-English-Amharic calendar, published every year from 1954 to 1978. Bogale was an early proponent of Ethiopian Jews praying in Hebrew instead of the ancient Semitic language, Ge'ez, as he felt that it was no longer appropriate for those seeking to be a part of the broader Jewish community. However, he did think that Hebrew prayers could be set to Ethiopian Jewish melodies to preserve some liturgical traditions of the Beta Israel community.
