The Catholic Church puts forward to the laity the example of many many saints, in their different dimensions (charity, chastity, prayer, sacrifice, etc), as inspiration to our own lives and challenges.
Relatedly, the Catholic Church asks homosexuals to be celibate, so as not to commit sin contra natura (and, given the more recent sexual abuse scandals, partly involving homosexual priests, the Church is more vocal against those who see the religious life merely as an alternative to an active homosexual life).
Are there examples of openly homosexual Christians who have taken the suggestion of the Church and "successfully" lived a celibate and fruitful Christian life, examples that the Church has put forward to others to imitate?
It is common to get into trouble when defending the position of the Church, not the least because it is considered unreasonable by non-Catholics. Yet, the existence of examples could help to "defend" better such position, in my view.
PS: the stress on "examples that the Church has put forward" is important here. It is not enough that others beside the Church (e.g. the "LGBT lobby") state that a given saint was homosexual (here?). What matters is that the Church takes a stance on this. Hence the "according to the Catholic Church" qualification.
