"We need fewer angular, sharp-elbowed Calvinists who glory in what distinguishes their stance from others"

From this review by a person whose upcoming book is “Against Calvinism” we learn that

B) Calvinists are immature
C) Calvinists are deficient in their knowledge of church history and theology

With “friends” like these, who needs opponents?
