Today when the topic of Christian persecution comes up among western Christians, we tend to think of, or draw our opinions on the persecutions of early Rome. That period we've all read of in biblical oriented texts. The question IMHO, should be focused more so on "the root of persecution". What causes and how is it brought about. I think most here would agree it can be stated, Christian persecution is, in essence anti Christ. We don't have to look far to find anti Christ today given the rapid rise of atheism and apostasy. Not to mention the rapid growth and tolerance in and of certain non Christian religions.
I would suggest one do casual readings of the founding of Communist Russia and then perhaps the Ottoman Empire of the early decades of the 20th century. Both of which governments were committed to ridding themselves of all religious ideas. Atheism is/was central to the communist ideology of the Soviet Union and in great part demanded the destruction of Christian teachings. Atheism was considered to be more intellectual, virtuous, and desirable. The state then established atheism as the only truth and forbid open criticism. Those thought to break these laws were labeled enemies of the state which would/could lead to imprisonment or even death. This all began with subtle ways and means. What path are many countries on today? How about the U.S.?
Today we laugh at such characters as "Archie Bunker" for his frequent use of the word "commie" and "atheist". But I would challenge anyone to visit some of the non Christian message boards on the net and read some of the posts found there. Read comments posted in response to news articles concerning church, Christian values, science, etc. The absolute hatred of God, and Christianity is frightening and one can easily see a parallel to those attitudes mentioned above. I firmly believe the same potential threats face us today as those which were realities in the countries and governments I mention. Persecution takes many forms and if we take the time to be aware, listen and look around us we can see it. Not persecution to death, but persecution which tends to expand with increased hatred.
Again, visit some of these message boards, make a post with comments concerning, Jesus,or scriptures and read the replies or simply read the replies to comments another has made. You might be shocked in to reality. Then consider how many Christians might be intimidated to not respond, profess or confess Christianity, consider your personal reaction to what you read there, think of Peter then come back here with your report. I am very serious, this is a learning and eye opening experience. Today many tend to "admit" Christianity as though it is demeaning, a sickness or an indication of ignorance. How long before they/we deny Him? God help us!
