Archangel Gabriel channels his teachings through the trance medium Reverend Penny Donovan. She was a natural medium since childhood and was ordained in 1960 at the John Carlson Memorial Institute in Buffalo, NY. Rev. Donovan channeled Gabriel from 1987 to 1999 and wrote many books on his teachings.

Archangel Gabriel does not speak in flowery language, but in the everyday, colloquial vernacular, which makes his teachings extremely easy to understand and absorb. In the book Christ Becoming Gabriel explains the past-lives of Jesus. Throughout this lecture, he reinterprets many Bible stories, which provides the reader with the motivation of why certain events occurred. The book also focuses on the Life of Jesus, then how to live more like a Christ.
