Summary: A classic book of advice for young pastors and theologians.
I have previously read A Little Book for New Theologians: Why and How to Study Theology, which is intentionally an update of Helmut Thielicke’s classic. I saw that the original was on kindle for less than $5 and decided to read the original as well.
A Little Exercise for Young Theologians is short. I read it in two short sittings. Most of the chapters are only 3 or 4 pages long. Much of it is advice of a similar sort to the updated version I had already read. (I would advice reading both, but with some time between.)
