Calvanism should not be contentious. As one who holds to the "Doctrines of Grace", I know there can be many theological differences with our brothers of a more Arminian persuasion. However, that should never be the cause of anger, bitterness, or strife...especially if we claim to believe salvation (and the theological sanctification) of every believer is entirely in the sovereign hand of a faithful God working by His Spirit. We are not the Holy Spirit! Can we debate Sure. Can we disagree? Yes, but we must do so while seeking to keep the bonds of unity where they may be found with those who may not hold positions exactly as we do. A true "Calvanist" knows that their life's goal is never to make more Calvanists, rather it is to lift up the immeasurable qualities of Jesus Christ as demonstrated by the Gospel to all around us. God will work out everything else!
