The Declaration has reaffirmed that the Church does not have the authority nor capability to bestow a liturgical blessing on irregular relationships, including same-sex relationships. Pastoral blessings may be imparted on any individual to invoke God’s help and mercy in their life, to help them grow in holiness, and to come to a greater understanding of Divine Truth. Such blessings are offered to the individual, and do not validate nor sanctify their union with another person.
