Here's a link to a page with a free download of Michael Dubruiel's book The Power of the Cross.
It's in .pdf format.
Also on the page is a link to a series of interviews Michael did with Catholic radio station KVSS on the book.
St. Francis of Assisi taught his followers to reverence Christ and
his cross wherever they might find themselves. The prayer attributed
to St. Francis that begins, “Lord, make me a channel of your
peace,” was in fact not composed by St. Francis; it was misapplied
to him in a prayer book. The true prayer of St. Francis was one
he taught his friars to pray whenever they would pass a Church
or the sign of the cross made by two branches in a tree. They were
to prostrate themselves toward the church or the cross and pray,
“We adore you Christ and we praise you present here and in all
the Churches throughout the world, because by your holy cross
you have redeemed the world.”
The cross reminds us of the true Christ, the one in the
Gospels who was constantly misjudged by the religious figures
of his day. If we are not careful, he will be misjudged by us as well.
We need to worship him alone.
