It is also likely that an Orthodox church will be a riot of color in comparison with the simpler statuary of Rome’s churches.
Regarding the language of worship, Orthodoxy never had a single liturgical language like Rome did with Latin prior to the 1960s.
In Orthodoxy there is, however, the similar practice of praying the Jesus Prayer (“Lord Jesus Christ, Son of God, have mercy on me”) with a knotted prayer rope (or sometimes with beads).
Other brief prayers may also be associated with the use of the prayer rope, though there is not any corresponding system of imaginative systems of meditations as there sometimes is in Roman Catholicism. Purgatory was developed in 12th century Roman Catholic theology to explain how the dead can work off the residual debt accrued from sin prior to the Second Coming.
As a consequence of these differences, the doctrine of Purgatory is absent from Orthodoxy, just as it is absent from the faith of Rome prior to its introduction in the 12th century.
Orthodox Christians and Roman Catholics both believe in the real presence of Christ in the Eucharist. Transubstantiation as a Roman Catholic doctrine is the use of Aristotelian philosophical categories of “substance” (what makes a thing what it is) and “accidents” (incidental attributes of a thing) to explain how it is that the bread and wine of the Eucharist still appear to be bread and wine (in their “accidents”) while having undergone a change in their “substance” to be the Body and Blood of Christ.
