One thing I have always found beautiful about Catholicism is the utter fairness of it all.
What makes you think that I
don’t have a difficult time with it? I have not always perfectly followed the teachings of the Church, nor, being a sinner, do I now. It is easier for me than it used to be, because I have finally made my peace with some things I used to rebel against. Wasn’t a thing easy about it. But I’ve “been there and done that”. And who’s to say that things won’t change in my life? Tragedy happens every day. Obstacles get thrown in your path. You just have to take life as it comes, and try to do what God wants you to do in all things. Sometimes much easier said than done.
I am not a member of Opus Dei, I’m not “on their page” in all things (nor do I have to be), never been associated with them in any way, never will be. But I find some of their practices very useful. One thing I have found fruitful is what they call the “heroic moment”, when you rise promptly at the beginning of the day, make the sign of the cross, and say
“serviam” — “I will serve”. Another recommended practice is “forget that you exist”. I fail miserably at the latter, but it’s a good principle to have in your mind.
