"A member of this group ought to perform at least one act of mercy a day; at least one, but there can be many more, for such deeds can easily be carried out by anyone, even the very poorest. For there are three ways of performing an act of mercy: the merciful word, by forgiving and by comforting; secondly, if you can offer no word, then pray - that too is mercy; and thirdly, deeds of Mercy." (Diary, par. 1157, 1158)
The Third Aspect - Companions of the Franciscan Congregate of Divine Mercy (FCDM) are those - whether clergy, religious, or lay, Catholic or non-Catholic of any age - who wished to unite themselves to the charism of the FCDM through prayer and acts of mercy.
All that is required of Companions of the FCDM is that the person promises to do "one act of Mercy a day," and to pray for the "reconciliation of earth and Heaven." (Diary, par. 1158)
