The Vatican reacted swiftly after a Polish priest who served with the Vatican's doctrinal arm announced he's gay and has a partner on the eve of a bishops' synod on the family.

Monsignor Krysztof Olaf Charamsa held a news conference on Saturday in Rome, where he called on Pope Francis to revise the Catholic teaching on homosexuality.

On Sunday, Francis opened the Synod of Bishops, a three-week assembly of bishops from around the world that will look at issues facing Catholic families.

“My decision of 'coming out' is a very personal decision in the homophobic world of the Catholic Church,” Charamsa, 43, explained to reporters. “It has been very difficult and very hard. I ask that you keep in mind this reality that is difficult to understand for anyone who has not lived through an identical passage in their own life.”

“The timing is not intended to pressurize anyone, but maybe a good pressure, in fact a Christian participation, a Christian voice that wants to bring to the synod the response of the homosexual believers to the questioning of Pope Francis,” he added, his partner Eduardo by his side.

He called on the church to “open your eyes to the suffering of gay people, to their desire for love.”

In a statement, the Vatican called the priest's action “very serious and irresponsible” and said that he “will certainly be unable” to continue as a theologian at the Vatican.
