If I misrepresent what you are saying, then please forgive me. I do not intend to accuse you of anything. It appears, by virtue of your second post, that you are not seeking examples, as much as rules of guidance. In other words, you are seeking the How To’s more than the Whodunnits. Plainly, one could not fail to find multitude upon multitude of examples of strong, faithful Catholics who have lived exemplary lives as secular leaders of various kinds. To whit: Charles V of Spain, Louis IX of France, Charles Carroll of Carrollton, St. Robert Bellarmine, St. Charles Borromeo, St. Philip Neri, St. John Bosco, Ven. Pius XII, and Bl. John Paul II, to name a few.
Concerning the how to’s of living the Catholic life in the world, I can offer no better example than that of Christ and the saints. If we ignore their example as too lofty for “normal people” to follow, then we ignore the very purpose and definition of true leadership, and of their example: to bring others to God through Christ. As Catholics, we possess the fulness of truth; what is more, we possess the key to suffering in this world. Hence, every one of our sacrifices can be turned to good, through the inestimable Grace of God. True leadership and sacrifice are indivisible. Not one of the leaders listed above escaped great sacrifice for a righteous cause. They all endured ostracism, taunts, threats, fears, insults, and many other things. What brought them above all these evils was the manner the faced them: with love and consideration for their persecutors, and complete trust in the Wisdom of God for their salvation. Every leader is called to act in like manner. And no one ever said it would be easy. But Christ is there every step of the way, if we just look for Him. All it takes is a pause, a breath, a thought, and He will be at our side to aid us.
Many blessings to you all from Rome, the seat of the Church and of the martyrs, and Happy Easter.
P.S. There is a Catholic Judge on the Supreme Court: Clarence Thomas. He attends St. Andrew the Apostle Catholic Church in Clifton, VA. The more people we support, and the more we ourselves take up the reins, the more we will gain through our efforts. Nothing is beyond hope with Christ. One thing we cannot do is give up. If we do, then we throw away the fruits of victory already won for us by Christ. Keep trying. God bless you all.
