Early Christian observance of both the spiritual seventh-day sabbath and a Lord's Day assembly is evidenced in a letter from Ignatius of Antioch to the Magnesians 110. The Pseudo-Ignatian additions amplified this point by combining weekly observance of a spiritual seventh-day sabbath with the Lord's assembly. If Pseudo-Ignatius dates as early as 140, its admonition must be considered important evidence on 2nd-century sabbath and Lord's Day observance. According to classical sources, widespread seventh-day sabbath rest by gentile Christians was also the prevailing mode in the 3rd and 4th centuries.
