I think so. Our division makes Christ and the apostles liars, in a sense, by negating one of the primary things upon which they insisted. Doctrine is a second order activity; love and unity are first order activities. Doctrine arises out of who Christ is and who we are in Christ, which must be realized in mutual love and unity before we say a word about what it all means. Those realities transcend whatever we might say about them. Lack of unity makes those realities seem like fanciful fictions. So, being divided over doctrine is like putting the cart before the horse, and then getting rid of the horse because it doesn't pull.
