Four female protesters on Sunday attempted to deliver a message to Pope Benedict XVI: “In gay we trust.”

As the pope appeared in his Vatican studio window overlooking St. Peter's Square, the women protested his views on gay marriage. Each had the words “In gay we trust” written in black on their backs, and “Shut Up!” on their fronts.

“Homophobe shut up!” the protesters screamed as the Holy Father deliver his traditional prayer.

As security officials carted the women away from the square, they continued to scream, “In gay we trust.” The pope did not appear to notice the disturbance.

“Today we go with a message to pope: To shut up his mouth and not to give his advice to those people who decide to legalize gay marriage,” Inna Shevchenko, one of the protesters, told the AP. “Today we are here to protest against homophobia.”

The women were members of the Ukrainian feminist group Femen, which in November counter protested marriage equality opponents holding a demonstration in Paris.
