"We face enormous temptations when countries start approving sin and codifying it into law in order to justify it,” Itar-Tass quoted the patriarch as saying after the Sunday service in the Kazan Cathedral on Red Square.
Those who follow their conscience and "fight such laws imposed by the minority are subjected to repressions,” he added.
Kirill urged Russians to ensure that sin is never formalized in the rule of law.
"This is a very dangerous apocalyptic symptom, and we must do everything in our powers to ensure that sin is never sanctioned in Russia by state law, because that would mean that the nation has embarked on a path of self-destruction,” Kirill stated.
The patriarch pointed out that people have been convinced that the only value is the freedom of choice and no one has the right to infringe on that "even when a person chooses evil or a socially dangerous behavior.”
The Patriarch called upon Russians to fight for freedom from sins. "Where sin is elected through freedom, there comes death, terror and dictatorship,” Kirill said.
He asked people pray for the future of the country to prevent "the slavery of sin” that leads to the "self-destruction of the nation”.
Patriarch Kirill led a church service in Moscow on Sunday that honored the Icon of the Kazan Mother of God, one of the most revered relics in Russia. The liturgy took place at the Church of the Kazan Mother of God on Red Square, which has a copy of the revered icon.
The topic of same-sex unions have been heatedly debated in Russia. On June 30 Russian President Vladimir Putin signed a controversial law strengthening the penalties for "propagating homosexuality among minors”.
The so-called ‘gay propaganda’ introduces fines for propaganda of non-traditional sex relationships to minors, including in the media, on the internet and via viral adverts.
