The Greenleaf Guides give some hands-on projects ideas and divide up the readings, as SCM handbooks do. The main differences I see are
- SCM incorporates more books in the readings.
- Greenleaf gives discussion questions.
- Greenleaf’s Old Testament guide covers the whole Old Testament, whereas SCM covers it over two years and in two different handbooks.
You might find it helpful to download the sample of the SCM handbook so you can compare it with the Greenleaf guide that you have in hand.
