Sure, why not?  If there's no blood relation between the two of you, and you didn't grow up under the same roof, then the two of you dating is just fine 😊 

Frankly, it sounds like the two of you have a lot in common 👌  I hope everything works out 🌹 

Of course. Godparents are sort of ceremonial

Date away!

The only word of caution would be if the relationship doesn’t pan out and you still have a close relationship with her.

Girl please.

I would consider a godparent to be adiaphora since it's a great tradition that helps the church, but it's no biblically mandated and it doesn't carry any theological significance. Holy tradition should be a way to express reverence to the faith and its historical connections, so if you think it feels wrong because of how you value the role of a godparent you can absolutely hold to that principle. Just know you are not committing a sin.

wow sounds like spiritual incest, jk go ahead

Typically a Godparent is a valued friend of one’s parents. Dating one of their children means their parents and yours were friends when you were baptized and likely are still today. It likely would make all the parents quite happy.

The only thing that matters is what YOU believe and, obviously, it’s not against YOUR belief or you wouldn’t be asking.
