The Catholic Church, as with other Christian institutions, will become irrelevant unless they distance themselves from the Democrat Party and the Liberals. These Christian institutions were originally sucked in by the Liberal facade of helping the poor, etc., etc. and the the Church failed to adapt as the Liberals became the party of "What's Happening Now!", be it love of homosexuality, ridicule of traditional families and fathers, love of Muslims, all of the Liberal Democrat programs that attract the unusual among us. The "Helping the poor" routine for government, of course, is to steal from those who don't vote Democrat and reward those who do vote Democrat.
The Catholic Church will have to loudly and affirmatively renounce the Democrat Party, Muslims, homosexuality, pop culture, Hollywood, large Socialist government and all of the things the Democrats are using to destroy America or the Church truly will become irrelevant.
Christians will not lose their faith, they will simply go elsewhere for a stronger affirmation of their faith and a stronger condemnation of the evil represented by the Democrat Party.
