To the shepherds alone was given all power to teach, to judge, to direct; on the faithful was imposed the duty of following their teaching, of submitting with docility to their judgment, and of allowing themselves to be governed, corrected, and guided by them in the way of salvation. Thus, it is an absolute necessity for the simple faithful to submit in mind and heart to their own pastors, and for the latter to submit with them to the Head and Supreme Pastor.
