https://site-catholique.fr/?Sermon-de-Mgr-Lefebvre-pour-la-Fete-du-Christ-RoiAI translation, Unofficial, Excerpt+L has a long paragraph re: getting involved in local politics , (not translated) Sound doctrine as can be expected from Abp Lefebvre. ********
"...We want Our Lord to Reign because He is the supreme King of all things, "omnium Regem supremum". We proclaim it and we want to proclaim it, not only for us personally so that Jesus Reigns in our souls by his Law, by His Grace, but we also want Him to reign in our families, in Christian families and in society. What is at the root of this apostasy is the denial of original sin. For if Our Lord Jesus Christ has come to earth and wants to reign in all souls, in all families, in all cities, it is precisely to make disappear and original sin and all its consequences, abominable consequences that lead to Hell, that lead to eternal death. He came to give us eternal life. If we deny original sin, Our Lord is no longer necessary. What does He come to do? Why is He coming? He comes to disturb our families, He comes to disturb the order of human freedom... But if we believe that really, there was an original sin of which all men are affected, with all its consequences, and that only Our Lord Jesus Christ is able to heal us, to bring us life, to purify us in His Blood and to give us His Grace, to give us His Law, then we turn to our Savior, to Our Lord Jesus Christ and we pray that He is our King, that His Law reigns everywhere, that His Grace reigns in all souls! That's what we say, that's what we think....
...This Feast exhorts us to act courageously, as Joan of Arc said in her fight: "We fight, we pray and God will give the victory". We will say: "Oh, it's impossible! We can't. It's too difficult, we will never be able to dominate the people who currently lead our countries. We will never be able to overthrow them..." But you have to count on the Grace of the Good God! The Good Lord is with us. The Good Lord wants to reign, the Good God wants the good of souls. Therefore, if the Catholics unite, pray, make sacrifices and campaign for the Kingdom of Our Lord Jesus Christ, we must count on the Grace of Our Lord, on the help of the Most Holy Virgin Mary who is "strong as an army in battle array" (Ct 6, 3), on the help of the Saints, Saint Michael the Archangel, all the Saints of the country, and here Saint Nicholas of Flue and Saint Maurice. Let us invoke them and ask them to help us so that Our Lord Jesus Christ reigns in our countries, to save our souls and those of future generations, and put our countries under the sweet reign of Our Lord.In the Name of the Father and the Son and the Holy Spirit. So be it.
