The short answer
Yes: as a Catholic Christian, you can use Christian Love Story, a free Christian dating site focused on marriage. Your profile states "Catholic", and once signed up you can filter profiles by denomination.
Finding someone who shares your faith
Every profile states its denomination, and everyone can say in their introduction what place faith holds in their life. You can look among Catholic Christians only, or open yourself to other Christian denominations: it is your choice, and you can say so in your introduction.
Talking about what matters
Mass, the sacraments, how you live your faith as a couple and as a family: these are topics best raised early. An introduction that simply says how you live your faith attracts the people who share it.
Signing up takes a few minutes
All you need is a photo that shows your face, a few honest lines about your faith and what you are looking for, your denomination and your situation. Every photo is checked before it is shown, and a person decides in case of doubt. Creating a profile, browsing members, writing and replying cost nothing, with no subscription and no card to enter.
Moving forward with confidence
Take time to talk on the site before you meet. For a first meeting, choose a public place in daytime and tell someone close to you. A sincere person will never ask you for money. Any member can report a profile, and a charter forbids pressure and inappropriate language.
FAQ
Is there a free Catholic dating site?
Christian Love Story is a free Christian dating site that welcomes Catholic Christians, like every Christian denomination. Every profile states its own.
Can I meet only Catholic Christians?
Once signed up, you can filter a country's profiles by denomination. You choose who you write to.
Are there Catholic singles near me?
Out of respect for its members, the site publishes no member figures and no public preview of profiles. Once you have signed up (the site is 100% free), you discover the profiles from your part of the world, and each profile shows the city.
Is it paid for men?
No. On Christian Love Story, men and women have the same rights and the same price: zero. Creating a profile, reading profiles, writing and replying are free for everyone.
How do I stay safe?
Talk on the site before meeting, meet in a public place and tell someone close to you. Never send money, and report any suspicious profile.
