A presentation of the nine major systematic Protestant theologies that dominated the 1960's. Summaries of each position are logically drawn and treated as living options before being critically examined. The first section of the book looks at theologians who are explicit in their philosophical commitment. The second treats those who seek in revelation an alternative to dependence on philosophy. In the third section, the author evaluates the existential mode of thought and those who espouse it. Originally published by the Westminster Press in 1962.
