Catholics are called for COMBAT; not for fearful isolation. We are not the Amish. We must be in the world but not of it. Christ has conquered the world and so, we must.
More than ever, traditional Catholics are needed everywhere, not only in small rural towns but in the cities and urban places as well.
Wherever God wants you to be, that is the place for you, because God knows best and He likes to have His children spread everywhere around the globe, giving testimony of the Gospel.
