No Catholic that I know has any obsession with either Luther or Sola Scriptura. Unfortunately, one cannot participate in any theological discussion in this Forum without Sola Scripture being made the predicate in any argument by Protestants. Each and every time "show me where in the the bible...." is presented in a disjunctive premise asserting that absence from Scripture is an automatic invalidation an appeal to Luther's authority is posed. The rejection of Luther and the premise dies not constitute an obsession with either.
I am disheartened that you feel so much animosity towards Catholics. We are not your enemies or even your rivals. We are your brothers and sisters in Christ. If you concentrate on our differences you will surely find them as you will find them between all individual believers. But if you concentrate on what we collectively love you will find we are united by something greater than any of us. I will leave you with this:
“Protestants, Jews and Catholics have God, morality, and religion in common. In the name of God, let us - Jews, Protestants, and Catholics - do two things: 1. Realize that an attack upon one is an attack upon all, since we are all one in God; it is not tolerance we need, but charity; not forbearance but love. 2. Begin doing something about religion, and the least we can do is say our prayers; to implore God’s blessings upon the world and our country; to thank Him for his blessings; and to become illumined in the fullness of His truth. There is entirely too much talk about religion and not enough action.” Archbishop Fulton J. Sheen
In general I do not hold animosity towards Catholics. I do tire of their arrogance, name calling and off the wall debate tactics. Occasionally I respond in like manner. The real object of my scorn is the institution of the Catholic Church and not its members. Its doctrines veer so far off the mark I feel I should respond to them. Maybe someone somewhere is warned off and will seek the Biblical God.
