"Sex and ‘rights’... someone, sooner or later, needs to spell out further (wearisome though it will be) the difference between (a) the ‘human dignity and civil liberty’ of those with homosexual and similar instincts and (b) their ‘rights’, as practising let alone ordained Christians, to give physical expression to those instincts. As the Pope has pointed out, the language of ‘human rights’ has now been downgraded in public discourse to the special pleading of every interest-group. The church has never acknowledged that powerful sexual instincts, which almost all human beings have, generate a prima facie ‘right’ that these instincts receive physical expression. Indeed, the church has always insisted that self-control is part of the ‘fruit of the Spirit’. All are called to chastity and, within that, some are called to celibacy; but a call to celibacy is not the same thing as discovering that one has a weak or negligible sexual drive. The call to the self-control of chastity is for all: for the heterosexually inclined who, whether married or not, are regularly and powerfully attracted to many different potential partners, just as much as for those with different instincts."
