Well, Eastern Orthodox Church Fathers teach that upon passing from this life, passing from the "Church Militant" to the "Church Triumphant," the soul receives a "Partial Judgment" and experiences a "foretaste" of the determination that will be made at the "Final Judgement." The soul does not experience time during this state. While Church Fathers encourage the faithful in this life to pray for those reposed, even asserting that the soul may sense a "temporary reprieve" from the prayers of the living, in their writings the Church Fathers acknowledge that they do not know whether these prayers will necessarily be efficacious, not-with-standing God's Judgement, because the effective result of prayers for the departed has no scriptural support. Fathers also teach that the "Church Militant" and the "Church Triumphant" join together in worship, "among the saints." The Orthodox Church does not teach of a state of existence in a "Purgatory;" "the purging of sins," none of the Roman Catholic teaching about Purgatory is taught in the Orthodox Church, neither does the word "purgatory" exist in Orthodox ecclesial terminology.
This morning the church observes the 2nd Saturday of the Souls, with a memorial Trisagion Service following the Divine Liturgy.
