Actually I was Orthodox ten years ago and rejoined the RCC in 2002. I was, for a while considering returning to the OC, but never officially made the jump over to your side. It has actually been over a year since I officially decided to stay with the RCC, only I delayed announcing it on this mesage board for some time until I was requested to publically do so by the moderators.
I probably always believed that the RCC was the true Church, even when Orthodox. I used to secretly think "Well, Catholicism is probably true, but Orthodoxy has a cooler liturgy and real beeswax candles to boot!" This is the basic reason that I decided to return to the RCC, because I felt that my Orthodox conversion was not sincere, but only a form of running away from problems that I saw plaguing Catholicism.
I admit that my above comments were kind of unflattering and nasty. I'm sorry things have been rough for me for the past couple week, but hopefully they'll get better. As a Catholic, the Vatican Council II called me to abstain from polemics and embrace the ecumenical dialogue with my brother Christians in charity, truth, and love. I obviously have failed to do so in my previous post. Vatican II and her spirit have called me, as an RC to be better then this and I'll try to be from now on.
