Although Roman collars, habits and wedding rings are widely recognizable signs of the wearer’s life commitment, these visual markers are customs, not requirements (except in the case of some religious orders that do require the habit.) The fact that a person is not displaying one of these signs does not automatically mean that he or she is available for romantic attachment: engaged people, those called to the single life and those who for the time being are not seeking relationships, for example, are also unavailable, but don’t necessarily have an easy way to show it. No one should be deceptive about whether or not he or she is open to an exclusive relationship. Thus a seminarian should be forthcoming and firm if someone approaches him with romantic interest, just as a married person would be forthcoming and firm to anyone who made an advance. But seminarians are not obliged to preemptively broadcast their status any more than the rest of us are, unless their diocese or religious order asks them to wear the Roman collar at particular functions or under certain circumstances. Some men in formation for the priesthood do wear the collar for various reasons; discerning a lifelong call to celibacy is not easy, and they may find that this distinction helps them in the process. But it is not required.
