Protestantism - horrors.   Really - and after John XXIII called the Second Vatican Council for the express purpose of ecumenism and addressing the *SCANDAL* of separated and divided Christian Churches.
From the opening address of VII by John XXIII:
Catholic church "desires to show herself to be a loving mother of all, benign, patient, full of mercy and goodness toward children separated from her," and "she spreads everywhere the fullness of Christian charity, than which nothing is more effective in eradicating the seeds of discord, nothing more efficacious in promoting concord, just peace and the brotherly unity of all." 
"In the daily exercise of our pastoral office, we sometimes have to listen, much to our regret, to voices of persons who, though burning with zeal, are not endowed with too much of discretion or measure." ..
"prophets of gloom, who are always forecasting disaster, as though the end of the world was at hand."

Cottage Industry - yep, Fr. Z, EWTN, the prophets of gloom
