The magazine contains a wide variety of articles, including exhortations from Breaking of Bread services, studies of Biblical characters, articles on Christian living, reviews of Bible-related books, and comment on relevant current events in relation to Bible prophecy.
Items for publication are produced by potentially any Christadelphian, pending the editorial process.
There is also a section dedicated to Christadelphian events and news from congregations, such as notifications of baptisms and deaths.
In addition to the magazine, other literature is published by the CMPA, including printed and electronic books, booklets detailing various Christadelphians beliefs, and Faith Alive, a magazine aimed at 16–25 year olds, which has been published since 1978.
