From RFI:
Anne-Charlotte had been thinking about apostasy, official renouncing her Catholic faith, for years before she finally wrote a letter to the parish where she was baptised in 1985.
“I announce to you, with this letter, my intention to renounce my baptism and to no longer appear in your registry,” she reads from the letter. Today she considers herself an atheist, having abandoned her faith as a child, when she was eight or nine years old. But never sought to officially renounce the religion, until now.
