A former commander of the Swiss Guard, the small force of men whose job it is to protect the pope, says there is "a network of homosexuals" within the Vatican, the latest in a series of claims about gay priests working at the heart of the Catholic Church.
Elmar Mader, who was commandant of the Guard from 2002 until 2008, said that his time at the heart of the Vatican had given him an insight into certain aspects of life there.
"I cannot refute the claim that there is a network of homosexuals. My experiences would indicate the existence of such a thing," he told the Swiss newspaper Schweiz am Sonntag.
Famed for their striking uniforms of blue, red and orange, recruits to the Guard swear to protect the pope and his successors with their lives.
Mader, 50, from the canton of St Gallen, refused to comment on speculation that he had warned guardsmen about the behaviour of certain priests.
Earlier this month, the same newspaper reported the claims of a former, unnamed member of the Guard that he had been the target of more than 20 "unambiguous sexual requests" from clergy while serving in the force.
Recounting a dinner in a Rome restaurant, the man was quoted as saying: "As the spinach and steak were served, the priest said to me: 'And you are the dessert'."
At the time, spokesman Urs Breitenmoser said the rumoured gay network did not pose a problem to the Swiss Guard, whose members, he said, were motivated by entirely different interests.
Asked about the claims, Mader reportedly said stories of this kind "obviously lacking in factual basis" were sometimes told. But the facts remained clear, he added.
"A working environment in which the great majority of men are unmarried is per se a draw for homosexuals, whether they consciously seek it out or unconsciously follow an urge," he said. "The Roman Curia [the Vatican's bureaucracy] is exactly this kind of environment."
Though it does not condemn gay people, whom it says should be "accepted with respect, compassion and sensitivity", the catechism of the Catholic Church teaches that homosexual acts are "objectively disordered" and calls gay people to abstinence.
Mader, while he said he did not have a problem with homosexuality, said he feared that a network or secret society of gay people within the Vatican could pose security problems. He added that he would not have promoted a gay man in the Guard - not because of his sexuality but because "the risk of disloyalty would have been too high".
Mader said: "I also learned that many homosexuals are inclined to be more loyal to each other than to other people or institutions.
"If this loyalty were to go as far as to become a network or even a kind of secret society, I would not tolerate it in my sphere of decision-making. Key people in the Vatican now seem to think similarly."
The comments appeared to be referring to a remark by Pope Francis on the flight home from Brazil last summer. "They say there are some gay people here. I think that when we encounter a gay person, we must make the distinction between the fact of a person being gay and the fact of a lobby, because lobbies are not good," the pontiff told journalists. He also joked that, while there was a lot of talk about a gay lobby, he had never seen it stamped on a Vatican identity card.
Francis signalled a clear conciliatory tone on the issue, and added: "If they accept the Lord and have goodwill, who am I to judge them?"
Mader's comments about the supposed threat posed by gay guards and priests drew criticism among rights advocates in Italy.
"Along with all gay people in the armed forces, I would advise Mader to become better informed," said Aurelio Mancuso, chairman of Equality.
Spanish cardinal criticised for calling homosexuality a 'defect'
Pope Francis' newly chosen Spanish cardinal, 84-year-old Fernando Sebastian Aguilar, came under harsh criticism for describing homosexuality as a "defect" that can be corrected with treatment.
"A lot of people complain and don't tolerate it but with all respect I say that homosexuality is a defective way of manifesting sexuality, because that has a structure and a purpose, which is procreation," Sebastian told the Malaga newspaper Sur.
The interview was published on Sunday, a week after the Spaniard was named as one of 19 new cardinals to be officially appointed on February 22.
"We have a lot of defects in our bodies. I have high blood pressure. Am I going to get angry because they tell me that? It is a defect I have that I have to correct as far as I can," said Sebastian, who is the archbishop emeritus of the northern city of Pamplona.
"Pointing out a defect to a homosexual is not an offence. It is a help because many cases of homosexuality can be recovered and normalised with adequate treatment," he said.
Spain's main opposition Socialist Party said such comments helped to "perpetuate the discrimination and violence that exists in many countries" against gays, lesbians and transsexuals.
