The celibate priest, and the married priest in the Eastern Rite, have to be models for the flock and also have to give an example that the redemption also encompasses the body and the bodily passions.

And it would be an abuse of power to discipline those who insist upon an orthodox interpretation of this encyclical and of all the papal magisterial documents. Only he who is in the state of Grace can also fruitfully receive Holy Communion. This revealed truth cannot be toppled by any power in the world, and no Catholic may ever believe the opposite or be forced to accept the opposite.
