It is hard to imagine Jesus telling anyone to "Go away; I do not know you." However, it does seem just, if we consider that these people actually had every opportunity to know him, and they chose to neglect every moment of grace that came their way. Jesus told his disciples, when he sent them out to preach "If people in a town do not receive you, shake the dust of their town from your feet, and go on your way..." They were offered a gift and they chose to reject it. Yes, we may have ate with him, he may have heard him speak to us through our priests, but the question is did we accept him? Don’t let the opportunities Jesus offers pass you by. If today you hear his voice, harden not your heart.
