Since I have listened to everyone's advice on the issue regarding baptism and Chrismation, I decide that I should follow Father's advice now and see if I can obtain the baptismal certificate or a certified letter of my previous heterodox baptism, and discuss with him what should be the proper way for me to be received into Orthodox Church, according to the Will of God, either Baptism or Chrismation.
Since my heterodox baptism was done in an evangelical, low Church protestant community, I guess the possibility for it to be recognized by Orthodox Church is very little... But I will still try to obtain it first and see if Orthodox Church recognizes it.
So, I guess the follow ones are quite important for me to know in obtaining a certificate/certified letter
1. Date when I was been baptized?
2. How I was been baptized? Immersion or Sprinkles?
3. What formula I was been baptized with? (e.g., in the name of the Father, the Son and the Holy Spirit)?
4. the name of Christian Community, The statement of faith of the community who I was been baptized?
What else I should be pay attention or be awared of? Thank everyone for advice!
My Aunt, uncle and my grandmothers on my mother side are regular attendants of the same Christian community I have mentioned above. They asked me why I need to obtain it and I haven't told them anything about Orthodoxy. They kept asking me what kind of Church I want to attend but I did not answer them, since I think they highly dislike Catholic Church and I fear that they might mix their thoughts regarding Catholicism and Orthodoxy together. I fear they might against Theotokos, Icons, Saints. So I guess I would just not tell them now.
Again, thanks everyone!
