Why do we only pray for and bless those who have passed on but have not been recognised as saints?
Do Orthodox Christians pray for or bless the dead saints and Virgin Mary in their prayers?
No. We pray for those who have passed on but have not been recognised as saints, but those that have been are venerated and asked for their prayers instead.
Virgin Mary and dead saints are our brother's and sisters as well.Why can't we pray for and bless the dead saints and Virgin Mary?
We already do...
"Again, we offer this spiritual worship for those who repose in the faith, forefathers, fathers, patriarchs, prophets, apostles, preachers, evangelists, martyrs, confessors, ascetics, and for every righteous spirit made perfect in faith.
Especially for our most holy, pure, blessed, and glorious Lady, the Theotokos and ever virgin Mary... For Saint John the prophet, forerunner, and baptist; for the holy glorious and most honorable Apostles, for Saints(s) (Name(s)) whose memory we commemorate today; and for all Your saints, through whose supplications, O God, bless us. Remember also all who have fallen asleep in the hope of resurrection unto eternal life. (Here the priest commemorates the names of the deceased.) And grant them rest, our God, where the light of Your countenance shines. Again, we ask You, Lord, remember all Orthodox bishops who rightly teach the word of Your truth, all presbyters, all deacons in the service of Christ, and every one in holy orders. We also offer to You this spiritual worship for the whole world, for the Holy, Catholic, and Apostolic Church, and for those living in purity and holiness. And for all those in public service; permit them, Lord, to serve and govern in peace that through the faithful conduct of their duties we may live peaceful and serene lives in all piety and holiness."
