Over the past sixty years, the social acceptability of certain types of behaviour has turned full circle, and is particularly true in relation to sexual behaviour of young people before marriage. Prior to the 1960's it was considered unacceptable that a young man and a young woman should live together before marriage. No doubt it did happen, but society did not condone it as it does today. In our secular and materialistic society, young people no longer learn about God and the Ten Commandments, and instead adopt a life-style and morality based on those of pop stars, film stars, and other so-called celebrities, portrayed in the media as representing ultimate success and happiness, but in reality an enticing mirage by which the young and impressionable are taken-in. Sadly, such life styles, often without any moral backbone, prove superficial and destructive, and lead only to disaster. The young and impressionable either do not see this, or choose to ignore it, until very late in the day, by which time great damage has been done to their own lives.Some time ago there was an excellent article published by the Abyssum blog-site, in which the teaching of the Church on these matters was re-iterated in a Pastoral letter issued by the Bishops of Pennsylvania. This letter was written in 1991, but the Church's teaching on faith and morals does not change, and applies just as much today as it did then, as it has done since the time of Christ.
We kid ourselves if we think that our Catholic sons and daughters are somehow immune from the influences of their peers. Sadly it is a fact that cohabiting has become so common in our western society, that many young Catholics see nothing wrong in this, after all everyone does it. Of course they are wrong, but human weakness exploited by Satan and his worldly cohorts, leads to moral blindness and sinful lifestyle, which if persisted in, will ultimately lead to hell.
