That is to expect to be persecuted in this world for your faith. The pluralistic society in which we live in today would label Christ and the apostles psychotic nuts.
People in modern society only want a Christ that fits their own lifestyle.
This is the false Christ,and in a sense the anti-Christ!
I suggest you read this thread I started.
The Beatitudes cannot be taken alone: they are not ideals; they are hard facts and realities inseparable from the Cross of Calvary.
Sounds like Bishop Sheen thought the Beatitudes, like the cross of Calvary, were addressed to all those who believe in Christ, not just to the Apostles.
First of all, I want you to reread Mark 9:38-41.
That is to expect to be persecuted in this world for your faith.
Next, I want you to reflect on the Ugandan Martyrs (I'm sure you've heard of them: the Catholic ones were canonized by Pope Paul VI) and remember that quite a few of them were not Roman Catholic, and understand just what this means.
Thank you for posting that reflection on the Beatitudes by Archbishop Sheen. It's wonderful stuff, and I've come to expect nothing less when I read his writings.
