Welcome to CAF!
…Then recently I met a relative of my bio dad who claims she was my Godmother and that I had been baptized in the Greek church. I consider myself Catholic and am not interested in changing my faith. Does that “other” baptism invalidate my sacraments and do I have to go through any processes to be fully Catholic?
Thanks
You are fully Catholic.
As Br. David said, if you were indeed Baptized in the Greek Orthodox Church then you were validly baptized. Most probably you received Chrismation (Confirmation) and Holy Eucharist at that same time in the Greek church. Orthodox and Eastern Catholics celebrate all three of these Mysteries/Sacraments at the same time, at any age, including for infants.
One can only be validly baptized one time so if you were baptized in the Greek Orthodox Church (or elsewhere for that matter) then the “baptism” that was done later in your adopted family’s church had no effect- no benefit, no harm- because you already were baptized.
Your Greek Orthodox “Godmother” should be able to tell you where those Sacraments took place. I assume Orthodox Churches keep good records of these Holy Mysteries/Sacraments and so you could get a copy of that record .
If an Orthodox wishes to come into the Catholic Church nothing is required other than the desire to do so, I think usually in conjunction with confession and Eucharist, so you have truly been Catholic during all those years.
If one were baptized Greek Orthodox then normally one would have been recorded as the Eastern Catholic Church counterpart, Melkite I suppose, upon coming into the Catholic Church, even when that occurs in a Latin parish. However being adopted by a Latin Catholic family probably vacates that . Your chancery could answer that, and maybe a canonist here can.
(It is also with permission possible to have Orthodox Godparents in the Latin Church, so a Greek Orthodox could have still been your Godmother at your Baptism in the Latin Church. I assume this isn’t what happened in your case. It sounds like she told you the Baptism was in an Orthodox Church.)
I was at Orthros and Divine Liturgy in a Greek Orthodox Church this morning. Today is a very special day – the Protection of the Mother of God-- and my Eastern Catholic parish was unable to celebrate it. There is such wealth in the Greek Orthodox Church. I hope that this reconnecting with your Greek Orthodox “Godmother” might be a chance to enjoy some of your paternal heritage. It sounds like your birth father did what he felt was best for you, and indeed that you had a faithful upbringing, thanks be to God. May this recent reconnecting with this part of your family also serve to enrich your life in the Most Holy Trinity!
Glory to God in all things!
