The fact is that in the 1950s the Divine Mercy Devotion
was suppressed and Sr. Faustinas diary was on the index of forbidden books. It was only rehabilitated around the world by John Paul II after Vatican II. In addition to that, it’s popular among the Charismatic Catholics, and
it seems to be used as a substitute for the Rosary.
Charismatic “Catholics” are just faux Protestant Pentacostals. Of course they would fall for this feelings oriented “Divine Mercy”.
Mercy is not a “feeling”. Mercy is God’s premiere and eternal gift to us.
If you don’t want to believe in the Divine Mercy devotions, that’s your choice.
But no one can deny the mercy of God. It is the message of the Gospel. It is the message of the Cross. It is the reason for our Faith.
Dear Lord, have mercy on us—we who are sinners.
