As Philip said ,i meant Catholic laymen leaving the C Church and becoming Orth priests
I thought it was bad for any Catholic to leave the the CC and go into schism by going to Orthodoxy ??
and not only that ,if they were to become clergyman or Priests of that schismatic church ,wouldnt that be even worse??
or maybe the whole 'schismatic' thing doesnt apply these days anymore ?? and Orthodoxy is no longer seen as schismatics??
The Catholic Church's position towards the Orthodox has become highly nuanced, particularly since the time of Pope John XXIII, who spent many years working with the Orthodox in traditionally Orthodox countries. We no longer speak of the Orthodox as "schismatic" but as "Sister Churches" (the Orthodox Church, like the Catholic Church, is actually a communion of a number of particular sui iuris or self-governing Churches). Also, the mutual excommunications that were issued in 1054 were lifted by Pope Paul VI (I think) and Patriarch Athenagoras.
The Catechism of the Catholic Church says that the Orthodox Churches have an "imperfect communion" with the Catholic Church since we pretty much share the same Faith, minus communion with each other, and that they possess the full means of salvation. Their Sacraments are totally valid and licit from the Catholic perspective.
The "us vs. them" mentality has been dropped, thanks in large part to attempts at an unbiased study of the history of the 1054 Schism. The Catholic Church now officially recognizes that She is just as much to blame for the Schism and its perpetuation as Orthodoxy - Catholicism perhaps more so since the Pope is supposed to function as a symbol of unity in the Church and not a source of division (the over-centralization of the Catholic Church being one of the sources of division with the Orthodox). It is for this reason that both John Paul II and Pope Benedict have called for a reformation of the Papacy along the lines of the experience of the First Millennium, while keeping in mind the peculiarities of modern times.
Finally, the Catholic Church has officially condemned proselytism, the attempt at converting individuals or groups of Orthodox faithful to the Catholic Church. Proselytism is in part what led to the formation of the majority of the Eastern Catholic Churches (with a few exceptions), which were once part of Orthodoxy. Such methods, instead of serving the ultimate goal of unity, actually only led to further divisions with the Orthodox. Of course, if an individual Orthodox person approaches the Catholic Church wanting to be received within Her communion, the Church will not refuse them. But the method of going out and trying to make "converts" from Orthodoxy to Catholicism has been condemned.
I don't really know how the Church feels about members who become Orthodox. Among Eastern Catholics it's not seen as being a very big deal, especially in their home countries, and most especially among the Melkites. This is so because families in these countries tend to be a mix of Orthodox and Eastern Catholic faithful, and going back and forth between the two is quite normal. Whether or not the Church officially frowns on such a thing, I do not know. I've never heard an official condemnation of it.
