What little I've read by Faggioli (and a little is too much) indicates that he 1) considers theology to be merely what is opposed to the Council of Trent, and 2) has been influenced by studying "theology" in Germany--which of course means that it was influenced by Hegel.
He seems to be an Historicist, i.e., statements of dogma are nothing else than a subjective comment bound to a certain time and place. Once that epoch is gone, the statements lose their relevance.
Well, if onanism is not masturbation, what is it? @Frà Alexis Bugnolo
Genesis 38:
8 Then Judah said to Onan, 'Take your brother's wife, and do your dutyas her brother-in-law, to maintain your brother's line.'
9 But Onan, knowing that the line would not count as his, spilt his seed on the ground every time he slept with his brother's wife, to avoid providing offspring for his brother.
10 What he did was offensive to Yahweh, who killed him too.
From then on, the act of polluting outside the propper natural place, in the air, self-congratulating, has been called onanism...
