“Friendship arises out of mere Companionship when two or more of the companions discover that they have in common some insight or interest or even taste which the others do not share and which, till that moment, each believed to be his own unique treasure (or burden). The typical expression of opening Friendship would be something like, ‘What? You too? I thought I was the only one.’” - C.S. Lewis, The Four Loves

Salvation and Creation

Be Catholic first. Not conservative or liberal first. Not American or any other nationality first. Everything else should be secondary and subordinate to our Christian faith.

Great discussions

Join the most interesting and insightful discussions.

Beware of any Christian movement that acts as though the world is full of enemies to be destroyed rather than full of neighbors to be loved.

Beware of any Christian movement that demands the government be an instrument of God's wrath but never a source of God's mercy, generosity, or compassion.
