Hi. The three families you refer to – I mean the West Syriac family, the East Syriac family, and the Melkite/Antiochian family – are certainly an area of interest for me.
Anyhow, to the specific question of going-Orthodox … well, these kinds of questions are hardly ever cut and dried; but personally I’m rather skeptical of it. Even with Greek Catholics who have gone Orthodox, it saddens me, but I’ll at least say to myself “Well, it’s understandable that they wanted to reunite with their mother church (UGCC becoming Ukrainian Orthodox, Romanian Catholics becoming Romanian Orthodox, etc etc).” But when we talk about the Maronites, and the West Syriac family as a whole, it’s hard to say who’s the mother church and whose the daughter church.
Well … possibly people will read this post as a pointless ramble, but I’ll stop now. Obviously I haven’t given a complete comprehensive answer, but only brought in another factor (hopefully one that won’t heat this thread up even further

as it has become a bit of a hot-button thread).
