I admit we're not talking absolutes here, but almost.In my experience counseling and writing on this topic, everybody thinks (or at least we'll end up in one of the situations you just talked about.They tend to involve the sharing of many aspects of each other's daily lives and routines.
Why risk harm to your own heart or to that of a brother or sister to have a type of companionship that, outside of marriage, is arguably questionable anyway?
This brings me to my second argument against intimate one-on-one friendships between brothers and sisters in Christ. Men and women who are not called to long-term singleness and celibacy have a strong desire for companionship with a member of the opposite sex. As I've discussed before, Scripture seems to consider marriage (and children) to be a normal part of the progression toward biblical manhood and womanhood (see, among others, Genesis -28; -24; Matthew -41; Luke -36).
Close friendships by their very nature tend to involve extensive time talking and hanging out one-on-one.
They tend to involve a deep knowledge of the other person's hopes, desires and personality.
Would want to date someone knowing that he or she had a significant, pre-existing and ongoing emotional bond with another single member of the opposite sex?
If I were a single person desiring marriage, the answers to these questions would matter to me.
Ladies, might there be men who would have initiated with you but for their uncertainty about or discomfort with your intimate friendship with another man?
Guys, has a woman perhaps turned you down over questions about a woman friend you spend lots of time with?
Basically, the question seems to be how exactly single Christians should relate to members of the opposite sex in that large and awkward zone between "we've never met" and a deliberate dating or courting relationship. I won't repeat the full history lesson here, as several Boundless authors have already discussed it (Joshua Rogers most recently, in his excellent piece "Your Friendgirl Deserves Better").
Essentially, the historical reality is that until 30 or 40 years ago, long, intimate friendships between men and women in which each served as the other's emotional confidante, relationship adviser and "best buddy" were far less common than they are today.
So is the trend toward intimate friendships between single men and women a good thing? If you haven't read my previous articles on biblical dating, you'll be helped in thinking through this issue by reading "Biblical Dating: How It's Different From Modern Dating." Based on some of the principles found there, let me offer a couple of practical reasons why I believe such friendships to be generally unwise, and then I'll suggest a positive role for friendship among singles in the Christian community.
