The Christian church is getting little excited by the increase year-on-year is adults seeking baptism. Especially in France and Belgium but also in the UK and in America. They are trying to explain the rise as an outcome of the Covid19 pandemic and the way in which people were forced to confront their mortality. Also they are impressed by the religiosity of the Muslim immigrants. To me this latter is as much to say they are terrified by the changing demography and resultant changing values, of their countries.
No one says this rise is because they have the truth. Maybe that’s archaic.
