The Sabbath and the Lord's Day by H. M. Riggle
First published in 1922.
Sabbath vs. Sunday understandings build upon one's conclusions regarding the old and new covenants in general and how one views the Ten Commandments in particular. Most Christians will be quick to give homage to the Ten Commandments and in so doing fall for the sabbatarian argument, "If the Ten Commandments are still binding today, then why don't you keep the Fourth?" Riggle tackles this difficult subject head on and draws his conclusions straight from Scripture. His arguments are cogent and forceful. This is a book that gives needed answers for those who are involved with sabbatarian issues.
