Is it true that the catholic church went to other countries and forced our religion upon them? Did old catholics wage holy war on other religions? Did people actually flee thier old country in fear of the church? I thought the church was protected so this could never happen. How did the church change for the better sence then?
The Church has a 2,000 year history. Have SOME in the 2,000 years done these things, loosely defined as you have presented? Probably.
But one must not conflate this with the Church’s teaching or mission. We are all sinners, including Church officials, including Popes. All of us. We always have been.
And yet the Truth of the Ten Commandments was not limited to the righteousness of the men who carried the Ark of the Covenant about. They are true regardless.
The Truth of the Resurrection is not limited by Peter’s denial thrice of Christ. It is true regardless.
The Truth of the Catholic Church, Christ’s Church, is not limited because of crusading Popes, zealous missionaries, or Inquisitors who overstepped their bounds. It is true regardless.
How do we know Christ protects the Church?
The Church stands still, as she has since he founded it. The Gates of Hell have not prevailed against her. And will not.
There is no other community or church which can truthfully make this claim. That is precisely why they cherry-pick (when they don’t outright fabricate) historical excesses to try to undermine the Church.
