The tribute pulls back the curtain on the tight-knit dynamic between the "The Real Housewives of Salt Lake City" star and her only child, describing a bond that ran deep.

Why it matters

The Cosby family's Faith Temple Pentecostal Churches carry major significance, as Mary's grandmother founded the church.
