"It is better for a man to be silent and be [a Christian], than to talk and not to be one. It is good to teach, if he who speaks also acts." - St. Ignatius of Antioch
The great Dominican preacher, St. Vincent Ferrer (1350-1419), never hesitated speaking the Truth, no matter how uncomfortable it might make his listeners.
Why? He had one and only one concern - the salvation of souls.
