According to the cited story, the mob numbered about 300. Now, I admit that seeing 300 weirdos stream into my church in the middle of Mass would have taken me aback, too. But I'd like to think that after those initial moments of stunned immobility, my first impulse would have been to leave my pew to help throw them out physically.
The thing that puzzles me is that this was allowed to happen in a Latin American country, where men are supposedly so proud, even "macho." How many men were present in the congregation? I mean, real MEN? Yes, I understand that some formed a protective cordon around the main altar, and thereby prevented even worse abuse from happening. Good start. But what was the rest of the congregation doing, while the confessional was being tipped over, and while an altar was being defaced, while pews were being ripped out and carted into the street? I can understand being surprised for a moment, but then... well, the proper response of Godly men to goons like these was recorded 2,000 years ago in I Maccabees 3: "...be ye men of valour, and be in readiness for the conflict; for it is better for us to perish in battle than to look upon the outrage of our nation and our altar."
And ladies, I mean no disrespect to you by speaking of men, above; it's just that it's our job as men to sacrifice our lives for you, our families, and our Church. When we've all gone down fighting, it'll be your turn. Just let us have the first crack at 'em.
