"Both the spiritual and temporal power derive from the divine power; consequently, the temporal power is subject to the spiritual only to the extent that this is so ordered by God; namely, in those matters which affect the salvation of the
soul. And in these matters the spiritual power is to be obeyed before the temporal. In those matters, however, which
concern the civil welfare, the temporal power should be obeyed rather than the spiritual, according to what we are told in St. Matthew (22:21) ""Render unto Caesar the things that are Caesar's."" Unless, of course, the spiritual and the temporal
power are identified in one person, as in the Pope, whose power is supreme in matters both temporal and spiritual,
through the dispensation of Him Who is both priest and king; a priest for ever according to the order of Melchisadech, the King of kings and Lord of lords, Whose power shall not fail and Whose domination shall not pass away into eternity."

Which principle regarding the relationship between spiritual and temporal power is described in the provided text?

A) Spiritual power always supersedes temporal power in all matters.
B) Temporal power should be obeyed in civil matters, while spiritual power should be followed in salvation-related matters.
C) The Pope's power is limited to spiritual matters and does not extend to the temporal realm.
D) Both spiritual and temporal powers must always be in complete agreement in all matters.
