Evangelicalism teaches unity, while scripture teaches separation.
Evangelicalism teaches that differences in doctrine are not a hinderance to fellowship, while scripture teaches that adherence to sound doctrine is the ONLY basis for fellowship. Evangelicalism teaches pragmatism, or the idea that the gospel should be accomodated to the methods of the world, yet scripture teaches that God's work must be done in God's way to produce results of eternal value. Evangelicalism refuses to identify sin and unbelief among its popular heroes, yet the scriptures never cease to identify sin and to rebuke it plainly. Evangelicalism has a great love for the world's respect, yet the scriptures teach that the things esteemed by men are an abomination to God. Evangelicalism accomodates the philosophies of the world, like evolution and psychology, yet scripture calls the philosophies of men vain and hopeless.
