Private Devotions to Mary: The Rosary
There is among Catholic Christians the need and
the practice of private spiritual devotions. This private prayer
life is found among other Christians also. For example, some
Christians pray the Psalms daily; others prefer a form of
meditation, etc. The Bible requires neither of everyone.
The Catholic Church has not and does not officially teach or
proclaim a private devotion as doctrine or dogma, required
by faith or the practice of all believers.
As any individual Christian has
private devotions, so also has even
the  Bishop of Rome. Should even
these private devotions be performed
in public no universal teaching is
intended.
