By David Carlin, The Catholic Thing - If you’re a general and you wish to break the enemy’s line of defense, you find his most vulnerable point and attack him precisely at that point with an exceptional concentration of forces. When you break through at that point, there’s a good chance his entire line of defense will collapse. You will have won the battle, maybe even the war... Catholicism’s most vulnerable point, as it defends itself against the assault being made against it by present-day atheism, is its ancient teaching that homosexual practice is a great sin.
