Formally switching from one Eastern Rite to another Eastern Rite?

[Vico]

I was baptized and Chrismated (Confirmed) in the Antiochian Orthodox Church. I was Chrismated when I joined the Coptic Orthodox Church. I was received in the Catholic Church by a profession of faith. I had only my Antiochian baptism/Chrismation certificate as the Coptic Church didn’t issue me one.

The basic concept is that one’s baptism makes one a member of a ritual Church in which the baptism takes place, but this is modified based upon not switching churches from that of one’s father, so in practice the ritual church of the Catholic Father is the norm. When an adult is baptized (14 or older) the Catholic Father’s church is not considered. So, that makes you Greek-Antiochian (unless you meant Syriac Orthodox Church of Antioch). In that case Melkite is the correct mapping. Syrian, Maronite, and Melkite all have Sees of Antioch.

Thanks. I was an adult convert to the Antiochian Orthodox Church.
