Author: Islip Collyer, paperback, 205 pages. First published by the Christadelphian in 1959, this is the fifth printing published in 2015.
The articles appeared serially in The Christadelphian: PRINCIPLES (13 chapters) in 1923-24; and PROVERBS (19 chapters) at intervals during 1934 to 1938.
"Some of the articles reflect the discussions of the time when they were written, but that does not affect their abiding worth. The writer effectively contributed to the thought of the community in a style of writing distinctively his own. He died in 1953."
