Mike makes a good point here.
Some times we over emphasize Unity and Peace, at the expense of truth and Biblical doctrine.
Ephesians 4:1-3 I therefore, the prisoner of the Lord, beseech you that ye walk worthy of the vocation wherewith ye are called, 2 With all lowliness and meekness, with longsuffering, forbearing one another in love; 3 Endeavouring to keep the unity of the Spirit in the bond of peace.
