do orthodoxs eastern have devotions like roman catholics?

devotions to the virgin Mary under the different ad vocations, the devotion of the saints, the day of saint Jude, the novena of saint Jude
I know Eastern churches and roman catholic were one once but they are separated and each one has different rites and some beliefs are not the same.

Don't know

They trace the same roots of apostolic succession and are virtually identical in doctrine, including devotions to Mary and the Saints.

Yes! Both the Russian and Greek Orthodox Churches are schismatic Churches. They have the same rituals as the Roman Catholic Church. The Orthodox churches are recognized by the Catholic
church as being of the same theology, and philosophy as itself. They do not recognize the office of the Pope. Their Communion, and other sacraments are valid. The Virgin Mary, the saints are all venerated.
