John and Jane are atheists, they marry in a registry office but after a few years split up and get divorced.
John meets another woman (Hannah) who is also an atheist and marries her in a registry office.
A couple of years later John and Hannah fall in love with the Catholic Church and want to be Catholics, what happens to them?
Does the priest tell the they must part from each other as John is married still to Jane in the eyes of the church? What if they agreed to commit to a platonic relationship?
Just wondering how the marriage before Catholicism works.
