As if our God were powerless, and our kingdom was of this world. O ye of little faith. Catholicism was a carnal religion, responsible for starting a war in the holy land. They also used war to suppress what they called heresy. That's not the example given by the TRUE apostles however.
2 corinthians 10:2 But I beg you that when I am present I may not be bold with that confidence by which I intend to be bold against some, who think of us as if we walked according to the flesh. 3 For though we walk in the flesh, we do not war according to the flesh. 4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, 5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, 6 and being ready to punish all disobedience when your obedience is fulfilled.
