As St. Thomas the Apostle could see the life of Jesus and still remain blind to His Resurrection, and as to those people that Jesus spoke of: 'Happy are those who have not seen and yet believe,' this is the current reality of American Catholicism.
The first kind of blindness is inexcusable save the grace of God, raining down through repentance.
The first kind of blindness witnesses to, and personally experiences, the Divine Mercy of Jesus Christ in the sacrament of confession (Reconciliation), but still doubts the saving power of Jesus Christ in the world.
The first kind of blindness is thoroughly catechized of the Real Presence of Jesus in the Eucharist, through Scripture and Tradition, family and faith experience, yet fails to see Jesus in the tiny white host.
The first kind of blindness falls in love with the knowledge, technology, and ideologies of the world, and fails to see the gospel voice of Jesus Christ in the successors to the Apostles in the Pope and Bishops.
The first kind of blindness fails to embrace the Cross, and fails, like Thomas, to believe in the conquering Spirit of Jesus, and is conquered by the world in submission to abortion, euthanasia, gay 'marriage,' liturgical apostasy, socialism, contraception, hedonism, consumerism, skepticism, in dissent from Catholic Tradition.
The first kind of blindness dresses up like a Catholic, and takes up space in a Catholic Church, but does not desire true Communion with his, or her, Spouse. When social scrutiny comes near, Jesus is pushed afar--so far away as to become nothing to their spiritual vision.
And then there is the second kind of blindness.
Those who are forgotten, downtrodden, unemployed, rejected, raped, robbed, beaten, and, in an analogous sense, Crucified. Yet, through many hard years, they still cling to hope in a Merciful God and Rise daily to faith.
These, through their own wounds, get to touch the wounds of Christ.
"Happy are those who have not seen and yet believe."
