Now for my annoying point-by-point commentary!
1. Papal Universal Jurisdiction
2. Papal Infallibility
3. Papal Petrine exclusivism (i.e., that only the Pope is Peter’s successor)
4. Development of Doctrine (as seen by the West)
5. The Filioque
6. Original Sin understood as guilt transmitted via “propagation” (I’m told the RCC no longer believes this)
7. The Immaculate Conception of Mary
8. Divine Simplicity
9. Merit and Satisfaction soteriology
10. Purgatory and Indulgences
11. Created grace (vs. uncreated)
With some qualifications, I agree with all of these.
12. Painting of religious imagery contrary to the traditional forms. (For veneration and ecclesiastical use)
One this one, I'm going to depart. I actually like the artistic style of so-called "Western iconography." There are many beautiful icons of saints and events in this style. I do find Byzantine/Eastern icons far deeper theologically, the lack of realism allowing much more to be portrayed. The most common example I've seen is the Nativity of our Lord icon, in which Christ is often depicted in swaddling clothes much like grave clothes, and in a tomb recessed in a cave. This depiction cannot occur as such in Western style. Similarly, the depiction of Christ as a "little adult" in Eastern iconography, which is deep and beautiful theologically, cannot be done in the Western style.
Still, I don't see the theological "problems" with western iconography. I find it quite beautiful.
13. Gregorian Reforms, Vatican I, Vatican II, and almost every Post-Schism Council
14. Adoption of secular/heterodox music into liturgical worship.
Yes, although I would like to wade through the Reforms and Councils of #13 to hammer out those details.
15. Mandatory clerical celibacy
16. Use of Unleavened Bread
17. Self-Flagellation/Mortification of the Flesh
Ultimately, I accept these. Clerical calibacy is a perfectly legitmate local tradition. I prefer having a married priest, myself, but if the Bishop of Rome opts to enforce clerical celibacy, I see nothing wrong with it.
18. Allowing Priests/Bishops who have fallen into fornication to celebrate Liturgy/Mass
19. Sitting during worship
Not a theological issue. I'm quite thoroughly a "traditional" (I think so anyway) Eastern Christian, and don't like pews. However, if the Roman church uses them, that's their right, even if I don't like it. I much prefer standing and think it would be better in general (and Orthodox churches with pews bug me!) but it doesn't make them heterodox.
20. Punishment of heretics by temporal/physical means
We have both done this, and both defended it (some still do).
21. Legalistic theology
22. Faith built on science/reason
23. Satisfaction theory of atonement
24. Transubstantiation as dogma
I agree. #21 needs to be expounded, though. When I say this, I'm speaking of the system in the RCC that enforces the idea of a breach of legal contract with God, and that confession is needed to "clean the slate." Being a good Christian is often made into being a good lawyer and doing the right things. We see this is many of the devotions of the RCC as well (the promises of the rosary, scapulars, etc.) as well as in indulgences. This is not Orthodox.
25. Sacraments (vs. Mysteries)
The only issue I take with the RCC view of Sacraments is that they limit them to seven. I much prefer the "sacramental life" approach of the East that sets no official list and sees a mystery as any point at which God enters our lives and how we should live for such communion with God through the Church.
26. Assumption of Mary (vs. Dormition)
27. Kneeling/Prostrating on Sundays
Thankfully, the RCC no longer teaches the Assumption of Mary prior to her Dormition. However, they should disallow this thought as a "pious opinion." The Theotokos did die, and is important to our Tradition. The RCC should make this clear.
As for #27, these are local customs. While I prefer not kneeling/prostrating on Sunday (save at the epiclesis, in some places) it's not a roadblock to communion (and just a bothersome to me is the lack of kneeling/prostrating in many Orthodox churches for weekday services!)
28. Thomism and St. Augustine’s errors.
I would like to further expound on what these errors are, but I do believe there to be problems with Thomism and Augustinianism.
1. The authority of Ecumenical Councils over the Pope
2. The Essence/Energies distinction
3. Reconnect Confirmation/Chrismation back to Baptism rather than delaying it
4. Administer Holy Communion (both body & blood) to all Church members, including infants
5. Pre-Tridentine and Tridentine form(s) of Liturgy/Mass
6. Praying to the liturgical East
Yes. With disagreement about the allergy discussion above. There are instances where this is a legitimate concern, and have been evidenced by previous posters in this thread. However, I also admire the faith of those like St. John the Wonderworker who partook of Eucharist spat out by the woman infected with rabes. May we all have such faith.
7. Traditional fasting, including Wed/Fri fasts and all fasting periods
Yes. Although I would note that the West has an ancient and venerable fasting tradition that is separate from the Eastern. The traditional western fasting is what should be restored. By no means should the RCC be required to utilize Eastern fasting guidelines, to which they were never subjected.
8. Canons as guide rather than law (related to 22)
9. Traditional method of dating Pascha/Easter
Maybe? This was an ancient problem that was finally resolved at Nicaea. However, with the current calendar problem, I wouldn't make a fuss about this. Although it is my hope that the whole Church would celebrate the feasts together (and most especially Pascha).
But that's just my two cents, FWIW.
