The Resurrection of Christ occurred on the third day after the Savior's death on the Cross. This evangelical event signifies the Lord's triumph over sin and death and the start of a new world atoned by Jesus Christ.
This year, Easter celebrations among Orthodox and Catholic believers fall on the same date, according to the Julian and Gregorian calendars.
Festive Easter services will be conducted in all Orthodox and Catholic churches on the night of Saturday and Sunday.
In Moscow alone, festivities will be held in 243 churches. The largest crowds of church-goers are expected to gather at the Cathedral of Christ the Savior, St. Daniel Monastery and the Epiphany Cathedral.
Alexy II, the Patriarch of Moscow and All Russia congratulated Christians on upcoming Easter, and called on every believer to strengthen their families.
"You must take special care of your families to make them strong and harmonious, capable of raising new generations in the spirit of truth and honor," the Patriarch said in his Easter message.
Meanwhile, security will be tightened all over Russia during Easter celebrations.
Over 90,000 police and interior troops will ensure order on Sunday during Easter, First Deputy Russian Interior Minister Alexander Chekalin said.
"On Saturday night, temples and adjoining territories will be checked by police officers with dogs, and posts will be set up there," he said, adding that police patrols will be placed near cemeteries, because many people traditionally visit them during Easter.
