The crux of it is:
• The Church and Pope Francis reaffirm the solemnity of marriage and that it is solely a sacrament between one man and one woman.
• Blessings are an act of reaching out to God and asking for grace, which speaks to a desire to conform one's life to His will. We aren't given a strict formula for blessings, and Pope Francis encourages for blessing to be used pastorally, as an act of bringing God into someone's life.
• Any blessing for a person or persons who are are living an irregular sexual life are essentially to be treated as another other ordinary person asking for a blessing.
However, the blessing may not be dispensed in any way that might confuse it with an endorsement or making it seem comparable to the rite of marriage. It is not to be accompanied by the particular dress, occasion, date, etc, that a licit marriage would have. It is not to be something routinely dispensed by the priest, or have a regular formula that moves it from a spontaneous blessing administered in the moment of asking, to a formal ritual.
It's truly a shame how the media and certain anti-Catholics are twisting this story into something it isn't.
