and again, please forgive my misreading what you wrote. I was not trying to cause any problems.
I re-read my response later and fretted about what fireworks it might produce. So, it seems Proverbs 29:23b applies to how you handled it
... but he who is lowly in spirit will obtain honor.
All I can really say about the details of your reply, though, is that I find them a bit disturbing. Your answer comes across as saying, yes, the Orthodox allow people to pray to whomever they wish. A local parish could canonize someone. If that is truly the case, that bothers me. If it is not true, you are playing down the role of authority within the Orthodox church.
What I would add to that is that the authority is outside of ourselves, and consistently knows more than we do, and is consistently right, especially when we are wrong.
I could put together bits and pieces of what people have said (like Rus' comment above) to assemble an answer in the way I would give it. But none is as explicit as I would have liked.
I have a friend who converted from Catholicism to Lutheranism who once said something that seems to apply. He said the RCC is like a person who is given a picture of Jesus and it is a dear treasure to him. He doesn't want it to be damaged so he puts it under glass and into a frame. But his friends don't seem to understand how dear it is to him, so he puts garland on the frame to try to make it look better ... and then lights and flowers and other baubles ... until the picture is completely covered and no one can see it. None of the things that was added to the picture is inately bad, but by covering the picture they become bad because they obsure what was important in the first place.
The answer to the question about the Buddhist, IMO, is Christ and only Christ. Christ is what differentiates us. Without Christ, we are no different than the Buddhist, and so if we cover up Christ with other things, we eventually become no different than a Buddhist.
The Church
must keep that the focus. Baptism points to Christ because he instituted it (Matt 28:16-20, 1 Cor 1:10-17), and he gives the living water (John 4:13). The Eucharist points to Christ because it is his body and blood (Mark 14:22-24). Scripture points to Christ because he
is the Word (John 1:14). A Buddhist may "accept" Jesus as a great teacher or because of some silly mystical teaching, but if all of that were stripped away so that nothing stood between the Buddhist and Christ, that person would no longer be a Buddhist.
It may seem like I'm just preaching to the choir, but moving on from that point, no saint who truly is a saint would want to do anything but point to Christ. Veneration of a saint can give courage to the faithful, but we must always remember John 15:5 ... apart from him we can do nothing. As soon as we think a saint has some special power that we can access through that saint apart from Christ, then we have let something come between us and Christ. To say that the Church can discern the eternal fate of a dead saint is to say the Church knows what God knew when he judged that person - it is to give the Church a divine power. You can disagree with that by saying it was God who revealed this to the Church, but if you follow your own rule about taking lessons away from the story of Lazarus and the rich man (as I pointed out earlier), then you will hear what is said in Luke 16:31. God doesn't do that. No where in scripture does God ever explicitly reveal the eternal fate of anyone. It is something people infer from passages such as that of the Transfiguration.
Anyway, my answer is Christ, and for whatever its worth, I'll end my sermon there.
