Blessing sin is evil and obviously not the Gospel and preaching of Jesus. To bless same sex unions is affirming sodomy as if God would accept and condone this. God does not and Francis is an antipope. I cannot give money to the Catholic Church until this abomination is rejected by the faithful.
Like so many things Rome tries to mince its words to be purposely evasive and confusing on the issue.
I do wonder how long it will be before we hear, "the church has always everywhere blessed....."
