BERLIN — More than 230 professors of Catholic theology in Germany and other countries where German is spoken have signed a statement protesting the Vatican’s recent pronouncement that priests cannot bless same-sex unions, adding to dissent over the document.

The statement issued Monday declared that last week’s text “is marked by a paternalistic air of superiority and discriminates against homosexual people and their life plans.”

“We distance ourselves firmly from this position,” it added. “We believe that the life and love of same-sex couples are not worth less before God than the life and love of any other couple.”

The document released a week ago by the Vatican’s orthodoxy office, the Congregation for the Doctrine of the Faith, said Catholic clergy cannot bless same-sex unions because God “cannot bless sin.”

The congregation’s note distinguished between blessing same-sex unions and the Catholic Church’s welcoming and blessing of gay people, which it upheld. The document argued that such unions are not part of God’s plan and that any sacramental recognition of them could be confused with marriage.

It pleased conservatives and disheartened advocates for LGBT Catholics. The German church has been at the forefront of opening discussion on hot-button issues such the church’s teaching on homosexuality.

The professors’ statement, which was drawn up by a working group at the University of Muenster in Germany, said the Vatican note lacked “theological depth” and “argumentative stringency.”

It included signatures from professors in Germany, Austria, Switzerland and the Netherlands.
