Apparently written in anger, the book is disgusting for the polemic attitude of its introduction and for deceptively calling itself Catholic while boldly and arrogantly issuing challenges to Church Tradition.
The author's mistake is to differentiate between the will of God and the teaching of the Church on this matter; which is not possible to a 'catholic' Christian. He places himself over and above the Church. Thereafter, he is able to repeat everything that backs his own views, while dismissing without refuting everything that doesn't.
Chapter one presents the author's challenge blatantly, 'We now know far more than all those learned Fathers and Scholastic theologians, and with pastoral experience and the Holy Spirit *we can discern for ourselves what God wants*. And we now have a significant political presence. So you (referring to 'the Vatican', who is portrayed as the big, bad man) have to revise centuries of tradition to suit us.'
The author will settle for nothing less than a total acceptance of his own views, that, aside from that troublesome Catholic Tradition which has never addressed the problem sufficiently, the homosexual act it a perfectly moral expression of 'human love'. This assertion he will never receive from a theological tradition that values reason and natural theology.
