It is inaccurate to say that the Catholic Church is now approving or validating same-sex unions or unions which are outside of marriage. The declaration makes allowance for ministers to bless people in these difficult situations that they may be assisted by God’s grace along the path of conversion and salvation. It is also most clear that these are not liturgical blessings and are not to be offered in a manner including clothing, gestures or words that would risk confusing the blessing with a sacramental marriage
