The Use of Sunday for Meetings of Believers in the New Testament: A Response
S. R. Llewelyn's recent study on Sunday in the NT attempts to prove that first-century Christians were regularly meeting together on the first day of the week. His available evidence is sparse, and his conclusions lack cogent support. His effort to demonstrate that the offering in 1 Cor. 16:2 was in a Christian assembly falls short of proof. Likewise his argument that Acts 20:7 proves that Christians assembled to celebrate the Eucharist on Sunday is not coercive. Finally the inference that Rev. 1:10 points to Sunday as a time of regular Christian assembly is more than the language of the text warrants.[from publisher's website]
