I was wondering what the Catholic Church’s views were on my boyfriend and I sleeping in the same room? We weren’t in the same bed, just the same room, and I was later told that the Church doesn’t approve of this. Is this right?
Short answer: no.
Long answer: The Church has no explicit position on this issue, which is understandable because otherwise we would end up with 100000000 commandments that would take the form of legal provisions and everybody would try to find a way around them and lose sight of charity. Details are sometimes left to the informed conscience and this does not at all mean that there is no absolute or objective truth there. It means we’re responsible for making judgement calls in accordance with the teaching of the Church.
The teaching here at hand is that near occasion to sin is avoided. This means that if something pits you against temptation that’s hard to resist for you, then you need to avoid that something. However, there is no teaching to support a claim that e.g. staying in the same room is near occasion to sin. This is a matter of fact, not of principle. If it is near occasion of sin, then you want to avoid it. If it’s not, then you don’t have to.
Then there is scandal. You don’t want to give people impression that you’re sinning and condoning sin and to make them think sin is okay or otherwise challenge their faith. This does not mean that you’re inevitably culpable for rumours that prying people repeat behind your back.
Another important consideration is that a relationship is not a marriage. To a young person in love, a relationship may look like half a marriage, so to say, but it’s not. At this stage, you’re basically “discerning” (finding out) whether your boyfriend is a right man for you to marry. It’s natural that you’re attracted, you’re in love, you feel affection etc., but the girlfriend-boyfriend relationship doesn’t really come with a set of rights attached to it. It’s basically premarital discernment. For this reason, one should be careful with expressions of intimacy–after all, such relationships don’t always work out and then people have to split up and there are regrets when one finally marries someone else and would like to turn back the time to “undo” certain things from the past.
Besides, occasion of sin is not a trivial matter. It is easy to overstate it and it’s easy to forget oneself, be misguided by pleadings from the other person for (physical) affection, taken over by one’s own senses and hormones, thinking about the wrong things etc. It’s easy to justify things before one does them, but it’s very hard afterwards when one has some mess to clean up (I know something about that from experience).
