Jonathan Roumie based his accent on his father's Egyptian accent and his aunt's Palestinian accent because he thought using an American or British accent would be unrealistic.
The show began as a test video done by showrunner Dallas Jenkins that he filmed on his property in Illinois. He was able to use the footage to secure his first $10 million that he used to kick start the show.
The show derives its name from the meaning of "Christ". The word is Greek meaning "anointed one" or "chosen one". Another meaning is seen in how Jesus chooses his followers and asks them to follow him.
The show has biblical scholars from a variety of Christian denominations help to review scripts to ensure biblical accuracy, as well as contextual accuracy.
Jonathan Roumie explained in an interview shortly after filming season 2 that he met a young woman who told him she had contemplated taking her life but changed her mind after watching I Have Called You by Name (2019), breaking down in tears upon seeing ending, explaining she felt loved by God again feeling reminded that she had a purpose.
