By Bree A. Dail, National Catholic Register - Cardinal Müller called on the faithful to resist error by educating themselves in the truths of the Catholic faith… “In the face of growing confusion about the doctrine of the faith, many bishops, priests, religious and laypeople of the Catholic Church have requested that I make a public testimony about the truth of revelation,” the former prefect of the Congregation for the Doctrine of the Faith writes in the introduction to his document, published in February. “It is the shepherds’ very own task to guide those entrusted to them on the path of salvation. This can only succeed if they know this way and follow it themselves.”
