Christian, Muslim, Buddhist and Jewish leaders from almost 50 countries took part in the July 3-5 religious forum to discuss ways to deal with terrorism and xenophobia.
In his closing speech at the forum, Patriarch Alexy II said: "We, representatives of various faiths and denominations, were unanimous in condemning confrontation, intolerance, cruelty and terrorism."
"When we speak of this in one voice, the heads of states and governments, the public and the faithful should take heed," he said.
The Moscow religious forum's guests included Cardinal Walter Kasper, responsible for relations with the Orthodox Church at the Vatican, as well as the chairman of the World Jewish Congress, Syria's top mufti, an Iranian ayatollah, and Muslim, Buddhist, Catholic and Orthodox Christian officials from China.
Pope Benedict XVI did not attend, but he greeted the gathering from St. Peter Square in the Vatican.
A declaration summarizing the participants' views on the fight against terrorism, religious extremism, and xenophobia will be sent to the leaders of the Group of Eight industrialized nations, said the head of the Moscow Patriarchate's department of external church relations, Metropolitan Kirill.
The heads of state of Russia, France, Italy, Germany, Canada, the United Kingdom, the United States and Japan will hold an annual G8 summit in St. Petersburg in July 15-17.
