Amen!
Not only that what would be a better gift that you could give to the souls of those who passed from this life with out knowing the Truth that is found in Mother Church? The Mass is the greatest prayer in the world, and I believe we should have it offered often exspecially for those who do not, or did not know the power of the Mass!
It is a spiritual work of mercy to pray for the living and the dead, so you are doing something right by having a Mass offered for someone…even if they are not Catholic…
