Life in Christ
The moral life is a spiritual worship. Christian activity
finds its nourishment in the liturgy and the celebration
of the sacraments.
The precepts of the Church concern the moral and Chris
tian life united with the liturgy and nourished by it.
The Magisterium of the Pastors of the Church in moral
matters is ordinarily exercised in catechesis and
preaching, on the basis of the Decalogue which states
the principles of moral life valid for every man.
The Roman Pontiff and the bishops, as authentic teach
ers, preach to the People of God the faith which is to
be believed and applied in moral life. It is also incum
bent on them to pronounce on moral questions that
fall within the natural law and reason.
The infallibility of the Magisterium of the Pastors ex
tends to all the elements of doctrine, including moral
doctrine, without which the saving truths of the faith
cannot be preserved, expounded, or observed.
