"Becoming Orthodox is not leaving the Church. Last time I checked, Rod Dreher's Church has (using Catholic terminology) Apostolic authority through Apostolic Succession, valid priesthood, valid sacraments, valid Eucharist, Holy Tradition, and everything The One Holy Catholic and Apostolic Church always had and believed. Sounds like a "valid" Church to me."
I'm curious kosta: by this post do you mean to say that Catholics (in communion with Rome) should view with indifference the conversion of a Catholic to Orthodoxy? Or am I missing something here?
I would look at what drove them away and whether they will attend church and participate in the life of The Church or not. If crossing over means that they will spiritually come back to life, I would be happy. Indifference would be concern if they left The Church for some Protestant sect.
As it is, in the Orthodox Church, their souls will continue to receive sacraments and the Eucharist, make signs of the cross, worship the Holy Trinity, atted a 1600 year-old litugry that even Latin used to serve at one time, commmorate the dead, fast nearly six months of the year, baptize their infants, magnify and venerate the Ever-Virgin Mother of God, and other Saints, and live a life based on the Holy Tradition.
What exactly have they lost that should be of concern?
