It is a sin which will be
transmitted by propagation to all mankind
, that is,
the transmission of a human nature deprived of original holiness
And that is why original sin is called "sin" only in an analogical sense:
it is a sin "contracted" and not "committed"
a state and
not an act
This also means that
holiness and justice are not integral parts of our
, but Godís Will for the happiness of all people.
