all we need is to be as tough as a mustard seed...

R. Alleluia, alleluia.
Shine like lights in the world, as you hold on to the word of life. 

Gospel Lk 17:1-6
Jesus said to his disciples, “Things that cause sin will inevitably occur, but woe to the one through whom they occur. It would be better for him if a millstone were put around his neck and he be thrown into the sea than for him to cause one of these little ones to sin. Be on your guard!
If your brother sins, rebuke him; and if he repents, forgive him. And if he wrongs you seven times in one day and returns to you seven times saying, ‘I am sorry,’ you should forgive him.” And the Apostles said to the Lord, “Increase our faith.” The Lord replied, “If you have faith the size of a mustard seed,you would say to this mulberry tree, ‘Be uprooted and planted in the sea,’ and it would obey you.”
