“Contend for the faith which was once delivered unto the saints.” “The faith” was the body of truth given once for all. In the Book of Acts it is called the apostles’ doctrine: “And they continued steadfastly in the apostles’ doctrine and fellowship, and in breaking of bread, and in prayers” (Acts 2:42). Notice that the apostles’ doctrine is the first thing mentioned. Since that is number one on God’s church parade, our church is not a church unless it is doing just that. – Dr. J. Vernon McGee
