I am also renouncing the catholic religion. I have despised this religion for 50 years ,but did not think I needed to formally renounce it. However I have only recently realised that my name, along with millions of orther ex catholics is still being counted and used as a statistic for political and social influence. That is, it is giving the church power to continue its oppressive work.
My first letter asking for my name to not be used in this way is to
The General Secretariat, 64 Aitken St, Airdrie Scotland ML6 6LT. I will let you know how I get on!
