Here's an older video of a sermon by Fr. Girouard, on the subject of the importance of sacrifice, from 2012 or 2013, not long after his dismissal from the SSPX, for openly disagreeing with the new orientation of the SSPX.
Here are a few excepts from the last part of the video. He is of course speaking to his flock at his chapel (after having endured the trial of having to separate from the SSPX), but I think it can pertain to the greater Resistance as well:
"We read in the Gospel of today that the gates of hell will not prevail. He did not say that the gates of hell will not try to prevail, or will not seem to prevail, but he said they will not prevail. But in the meantime, they will attack and be so powerful that they seem to be prevailing, but will not prevail at the end.
The first Christians were the same kind of human beings that we are. The reaction of that little girl shows it. It was a very human reaction, and yes for them too it was tiring to be praying; it was tiring to be fasting; it was tiring to be persecuted, but they did it and they accepted the Cross, and God helped them. This is our mission as a little group to imitate their fervor, and to do all the sacrifices we can in terms of our daily life, our fidelity to the commands of God, our striving for modesty in dress and modesty in behavior, and humility, the practice of meekness, the imitation of Our Lord, the readings of the life of the saints, the readings of the Bible, of the catechism.
Yes, we have to sacrifice by making, maybe, if we read this book, if we do these good prayers, we have less time for recreation. I agree. It's true it's a sacrifice. But that's what I mean. We need to do these sacrifices. Because God, it is His will that He will use what we in philosophy call secondary causes. Yes, God could make a miracle today, God could change the hearts of everybody, but that's not the way He wants to operate.
He wants to operate through us, and that is why if we want to be true Resistance against the shenanigans of the Society, because the Society is now abandoning her role, the Society now, under the illusion of trying to change the Church from the inside, the conciliar church from the inside, the new Society, that's what they want. They should, instead, remain like they did, like we used to be. A power, or a little power, a little lighthouse that will stand on a rock, the rock of true doctrine, the rock of the true sacraments, and that will guide the ships. It is no use to be a lighthouse if you are inside the ship. That's our way to hell, the modern church […] It's not for us to go to them and adapt to them.
And so prayer, sacrifices and being steadfast on the rock of truth and the true sacraments, this is our program as the Resistance, and we must do more than we used to do. If we only want to do what we were doing at Christ the King (chapel), that is not enough."https://www.bing.com/videos/search?q=fr.+patrick+girouard%2c+youtube&&view=detail&mid=4EE5CABD205B4E7CCB9D4EE5CABD205B4E7CCB9D&rvsmid=32FA30257F634F69116432FA30257F634F691164&FORM=VDMCNR
