Here is a link to the
Episcopal Nicene Creed
Basically what he did was to replace the gender of the Holy Spirit from male to female.
I'm Catholic and not Episcopal, but I was confused about how you only change 2 references to God in the Creed. The Holy Spirit is still God, but it's definitely different than saying he changed God to being a female. God is still the 'Father' and Jesus "his son".
