I recently read a very good article on Christianity.com about Religious Tolerance. It perfectly explains how I have understood Religious Tolerance.
"Christians should always be tolerant of other religious beliefs but not accept them as the truth. Instead, Christians should respect and love others in their beliefs, but show greater love in sharing the Good News of Jesus Christ."
"The tolerance that was experienced in the classical era is quite different in the modern-day. In the classical era, Christians acknowledged that there were different religions and beliefs and accepted that people had the right to choose which belief they wanted to be in." Makes sense doesn't it? This is what my parents taught us. But as time passed and people became "enlightened" religious tolerance took on a different meaning.
"In the modern-day view of tolerance, acceptance is not only a matter of respecting other religions, but also accepting they are right and true." Wait a minute... RIGHT AND TRUE?? How did that get in there?? And WHY are so many Christians following this line of thinking?
The article points out that accepting that these beliefs are right, which is the modern-day view of Christian toleranc is where we, as Christians, need to draw the line.
You may be asking, "is religious tolerance a biblical principle?" Yes, in most definitely is!
"Christians should always be tolerant of other religious beliefs but not accept them as the truth. Instead, Christians should respect and love others in their beliefs, but show greater love in sharing the Good News of Jesus Christ."
