First of all, we need to be simple and down to earth enough to remember the BASICS. Namely, we need to keep the Faith and save our souls. Regardless of the Pope, regardless of the Church authorities and fallible churchmen.
We need to stay Catholic, both in doctrine AND in practice. So we need to know our Faith (which we can get from good faithful priests, as well as pre-Vatican II Catholic literature), and PRACTICE the Catholic Faith as much as we can. To keep the Faith in practice, we need to attend valid, doubt-free Masses and partake of valid, doubt-free sacraments.
But I think this is a key point which is often overlooked:
We need to spend a certain percentage of our waking hours on the positive elements of Catholicism, or JUST BEING CATHOLIC. That is to say, we must occasionally just kick back and enjoy the Catholicism we've fought so long and hard to keep.
If we can't do this anymore, we are close to a fall.
I will endeavor to explain.
Think about all the distractions and negative elements we have to deal with today:
Struggling against error, fighting, defending good priests, watching friends/family go astray, watching fellow parishioners disappear from our chapels (for various reasons), watching fellow Catholics give up and go various directions, temptations, attacks from fellow parishioners, attacks from rival groups, attacks from Modernists, attacks from Pagans around us, polemics we read online, reading the words of people who are in error and/or honestly confused, etc.
These things can be dealt with, but not unless we have a BASIC CATHOLIC CORE of just being Catholic. Once in a while we have to IGNORE the attacks, IGNORE the evils in the world, IGNORE the Talmudic Jews and Freemasons, PUT DOWN the pen and keyboard, and just ENJOY the Catholicism! Bask in the Catholic Faith we are still blessed to have. Talk (pray) to Our Lord and Our Lady. Go on a traditional silent retreat, or at least a 1 day recollection. Pray to your patron saint(s). Read Lives of the Saints and early Church martyrs. Read Holy Scripture. Pray a Rosary. Make a meditation or the Stations of the Cross. Make a spiritual communion. Volunteer to help out at your local chapel if you have one. Do something constructive for the Church. Try to convert someone to the Catholic Faith, if you can find someone the least bit interested (talking about a protestant or pagan here, not a Feeneyite, sedevacantist, or non-sedevacantist!). Listen to a CD of Gregorian chant or polyphony. Look at some beautiful Catholic art. Read the Doctors of the Church. Go to Mass. Go to Benediction. Go on a pilgrimage. Stay after Mass and talk with fellow Catholics, or at least visit another Catholic family. Enjoy some of the good things the Faith has to offer -- the smells and bells, as it were. These must be the consolations that God had in mind to keep us going during this Crisis. If we deny ourselves these sources of strength and consolation, it's no wonder we will fall. That is why I am so vehemently against dogmatic home-aloneism.
Without some of these positives, it's easy to DROWN in all the confusion and evil, and be tempted to despair.
I am sharing with you my secret for staying a faithful soldier -- a Traditional Catholic -- for so many years. All glory be to God, of course. But it doesn't help anybody to ignore/deny the fact that SO MANY Traditional Catholics are tempted to give up after X number of years. This has been true in the SSPX for a long time. Priests and faithful become tempted to end the war early by surrender -- by compromise with the world. They raise the white flag and negotiate a personal truce with the enemy, because they can't handle a war that lasts decades.
I know from personal experience that after I perform several items in that "Catholic activities" list above, I am ready to get back out there on the battlefield. But I really benefit from those breaks from the constant fighting.
In short, you just have to know when to call it a day, put down the books on the Crisis, take a break from CathInfo, etc. Better to withdraw from CathInfo for a week or two, than to lose your Faith! (Or maybe restrict yourself to the "The Sacred: Catholic Liturgy, Chant, Prayers" subforum for a week, if you have the discipline)
Different people can handle different amounts of "staring evil right in the face", and I think it has to do with how much "just being Catholic" they do in their spare time.
Some people it seems are ALWAYS fighting and never just enjoying the Catholicism they fought for. It's as if they've forgotten what they were fighting for. The fighting has become an end in itself. They can't see the forest because of all the trees in the way.
It's like a man full of anger who goes on vacation, but is constantly frustrated, upset and angry throughout his vacation. He is so stressed out, he has forgotten how to let go and just "enjoy the trip". He is so used to being negative, he can't enjoy his vacation at all because the hotel's breakfast buffet ran out of bacon, someone cut him off on the highway, he left the lights on in his rented car, or other minor inconveniences. He has forgotten how to let go of things.
What's the point of spending money/time on a vacation, if you've forgotten how to let go and have fun? What's the point of fighting hard to keep the Faith, if you've forgotten how to practice and live a normal Catholic lifestyle?
