HI I am starting this new forum after the number of responses to Albert's post, "Send many messages - fail to receive any response"
How many of us here on this Catholic site will not give a second thought to a profile that agrees to premarital sex.
For me it is a deal breaker:
1. I am on this site to meet a man who will help me get closer to my God - my first criteria is a man seeking to love God with all his heart.
2. Premarital sex is fornication <FULLSTOP> It is a mortal sin and separates me from the love and grace of my God
3. True love would wait. That teaches patience and perseverance -qualities that build a good relationship
I completely agree with your concerns about dating someone who is open to premarital sex. First, because of the risk the person will not be supporting you 100% in maintaining your chastity when the going gets rough (regardless of what they say initially -- not necessarily because they are being dishonest, but rather because they won't have the same commitment down the road).
The second reason is because they are not 100% committed to following the teachings of the Church. If they are willing to put aside the Church's teaching in this area because it is not convenient, what else might they decide they don't need to follow at some point?)
That being said, I think it is very important (for reasons I explained in Albert's topic) to make the distinction between the profile responses and what the person believes: you may recall the saying about the danger when you ass-u-me.
One thing I forgot to mention in the other topic is that there are many people with 7/7 faith responses in their profile who are less than honest in answering the questions. For this reason, it is important to discuss show stoppers such as this with every person you are interested in before the relationship gets too serious. If you are going to have the discussion with those who are 7/7, what harm is there is doing the same with those who are not? Yes, it may be a bit awkward; however, the more practice you get the easier it will become. And you may end up being pleasantly surprised.
