For most of the period 1937 to 1962 Carter worked to promote a broader range of content in the magazine, more outreach publications, and set in motion a series of New Testament Commentaries of which he himself wrote several volumes.

In Birmingham itself many Christadelphians adhered to the "Suffolk Street" grouping of which Thomas Turner was editor of the Fraternal Visitor magazine.
Although the position of editor carried no formal authority Carter was frequently invited to speak at Bible Schools in North America and Australia.
