Although recent speculation has focused on whether the pope will allow condoms in cases of HIV, the result can only be a resounding NO.
This is part of the faith of the Church, it cannot be changed.
This is a good illustration of how faith develops.
Contraception was fairly casually dismissed as obviously corrupt, liable to lead to adultery, and so forth, until the eugenics and sexual health movements of the early twentieth century, when it suddenly started to be promoted.
By the sixties it was very fashionable, all the Protestant denominations had accepted it, and the church was forced to think how to respond.
The developing consensus is that the sexual act must be open to the transmission of life. It is becoming more and more obvious that the secular position, that contracpetion is a good technical fix to the problems of unwanted pregnacy, is simply inadequate. Why, when condom machines are available in every pub, is one in three babies aborted?
However there is still room for fluidity in the church’s position. Rejecting the idea that sex education consists mainly of telling young people to make love with condoms on doesn’t mean that you necessarily ban all condom use, in all circumstances, and for all time. Until it is more widely accepted that contraceptives are part of the problem, and not part of the solution, however I cannot see the pastoral sense in any compromise on the no condoms, ever, rule.
