Even though I'm a Catholic which has a more significant belief on the role of the Church and also in some cases causes judgement from many reformed/protestant denominations. I have far more in common with my brethren who strive for uniformity to the will of the Father and have a relationship with Jesus rather than those who are "members of the Church" alone. It's sad when the internal presuppositions of individuals get in the way of that which unites us.  This can happen within any denomination within the Christian fold in both directions.
Lk 11:11 Which of you fathers, if your son asks for a fish, will give him a snake instead?
