More progress toward unity in the Church has been made in the past half century between Catholics and Protestants than in the past 500 years, according to Catholic philosopher Peter Kreeft.
There can never be unity based upon error. Yes, we can share some precious truths with others, but we must hold onto present truth i.e. God's purpose for our lives in this day. Without the Bible and proper interpretation, we have no answers.
Below is an article about the Spanish inquisition. Religious tolerance is given lip service, it will never happen.
"They [secret diaries] tell the story of religious intolerance that we shouldn't let happen again in the world," he says. "Despite that, it still happens."
The Religious Left and their Secular friends have so changed the English language, that:
"Love" = "Hate"
"Tolerance" = "Support for my ideology"
"Fundamentalist" = "Terrorist"
"Righteous" = "Evil"
It's getting more and more impossible to have any discussion with Liberals in the Church, as their superiority complex prevents them from having a reasonable conversation with anyone who doesn't think just like they do.
A LOT of this changing of the language has been carried about by the Roman Catholic Church, as their educational system is naturally set up to make their abominations look good in the sight of the masses. Sadly, we Protestants have bought into the language change, as our educational system is just like the Catholic one with PhDs, D.D.s, etc. So, slowly our belief system has been changed to where it is no longer based on the unchangeable words of God.
How I long for some schools of the prophets today!
Yes, language is a powerful tool, perhaps the most powerful. The meaning of words in the pacifism debate have also changed over time e.g. noncombatant.
