There are two basic types: general dating sites that have large numbers of people and those that are specifically Catholic dating sites.
You must take the initiative in attending to those whose faith and morals seem compatible.
They supplement helping people find matches by providing articles and advice columns about the Catholic faith.
Finally, they all charge around a month, lower if you sign up for six months.
Their weakness is that they have smaller numbers of users.
Catholic dating sites all function similarly to the general dating sites with profiles, search options, and messaging systems.
