The greatest threat to our Faith stems from the insidious effects of secular humanism and materialism which has corrupted and compromised so many professing Christians. The most severe persecution has come from secular states, mostly communist, and from radical Islamic regimes.
However, probably an even greater threat than these would be apathy within the Church. We need to know God and to make Him known. We need to be transformed by the renewing of our minds and understand the times, knowing what the people of God should do.
