It definitely changed me. The first thing it changed was it caused me to accept violence in just wars and self-defense, whereas previously I had a very Tolstoyan idea about violence. Self-defense and just war are moral acts according to God's Law to me, so I judged that I judged incorrectly.
Secondly, it changed my view of the political landscape by causing me to reject liberalism (defined as "the political doctrine which states that securing individual rights and personal freedom is a primary legitimate purpose of government," those called "conservatives" from my perspective are often arch-liberals) and the idea that the authority of a government somehow derives from the consent of those governed. I reject the first thing because the primary, possibly the only, aim of government is orienting and moving man towards God. Human law aids in this process, so do the other things government does (for instance relieving the poor from starvation, homelessness, bad health, mental illness, stupidity, illiteracy, etc, so that their minds will be elevated and free to be directed towards God). I reject the second thing because the Scriptures and Church in manifold places teach that authority comes from God/above, the idea that it comes from below is such a diabolical inversion of reality to me it is comical. The idea that any instituted authority (from father, king, priest, to God the Father Himself) depends on consent also gets the same reaction from me.
Thirdly, I became a Zionist, that is I desire for the State of Israel to exist and be preserved due to it. Zionism is taught by the Church in many places, including from an Apostolic Letter of Pope St. John Paul II saying: "After the tragic extermination of the Shoah , the Jewish people began a new period in their history. They have a right to a homeland as does any civil nation, according to international law. "For the Jewish people who live in the State of Israel and who preserve in that land such precious testimonies to their history and their faith, we must ask for the desired security and the due tranquillity that is the prerogative of every nation and condition of life and of progress for every society" (Ioannis Pauli PP. II Redemptionis Anno, die 20 apr. 1984: Insegnamenti di Giovanni Paolo II, VII, 1 (1984) 1072)."
Those are just three major ways (there are of course others, including on the environment, the liberation and self-determination of my race, and so on) in which my political ideas were influenced or caused by my religion. The Lord Jesus said "all authority in Heaven and on Earth is given to me," He is the Lord of all areas of life, so really I do not see any separation between politics and religion (religion being the bond between man and God), or between Him and anything, for all things exist "through, by, for, and to" Him.
That's my opinion at least.
