Many of our churches now value the Inclusivity of everyone in including those even non-religious. Everyone is welcomed. Many moons ago when I was a young girl; only those who had been baptised/christened could be godparents.
By the time I had my own family, the church was more inclusive and would except those who were willing to pray and believe in the faith of good etc irregardless of their religious background. Some of my children’s godparents are not religious nor have been baptised, yet they would still pray even when my child has been quite unwell/in hospital.
I think it depends where you are (in the uk) and the religion. MOO of course, Church of England, and where I am, anyone who is willing to care, pray and protect someone else’s baby is just as important as religion. Times changed so much and the church’s here have become more inclusive to ALL.
