Russian President Vladimir Putin has brought a number of new constitutional changes to Parliament, including amendments that mention God and state that marriage is a union of men and women.
Putin sparked a political storm in January by proposing a revision of the constitution, the first changes to the Basic Law since 1993.
Last month, the House of Commons of the Russian Parliament unanimously adopted the constitutional reform law at first reading after less than two hours of debate.
Putin submitted 24-page amendments ahead of a second and key reading for next week, State Duma spokesman Vyacheslav Wolodin said.
"The President's amendments are the result of his dialogue with representatives of all political groups (and civil society)," he said in State Duma comments.
The amendments anchor the mention of "Russians' belief in God" and also provide that marriage is a heterosexual association, deputy spokesman Pyotr Tolstoy told AFP.
Most Russians identify themselves as Orthodox Christians, but Russia is officially a secular state.
The new changes also prohibit the allocation of Russian territory, and any call to promote such a move would also be prohibited.
A member of a constitutional working group appointed by the Kremlin, actor Vladimir Mashkov, has suggested that such a change would ensure that Russia – the Crimea – which it annexed from Ukraine in 2014 – or the Kuril Islands – has been controversial with Japan for decades – even after Putin has left power.
Putin, 67, who has dominated Russia for 20 years, has attempted to defend traditional values and support by promoting anti-Western and conservative ideas.
Putin's fourth visit to the Kremlin was a strong linchpin for more conservative politics, with groups that advocate fundamentalist-orthodox Christian views gaining more legitimacy and attacking liberal positions as Moscow's relations with the West became sour.
The second reading of the constitutional reform law is scheduled for March 10, said a spokeswoman for Pavel Krasheninnikov, co-chief of the constitutional working group.
The spokeswoman informed AFP that the text of the amendments is expected to be released later this week.
A public vote on constitutional reform is scheduled for April 22.
Analysts see Putin's plan to change the constitution as the start of preparations for the successor when his current term in the Kremlin ends in 2024.
Over the weekend, more than 22,000 people gathered in central Moscow to urge Putin not to remain in power indefinitely.
