Buchik,
That could be dangerous off the shores of Oz; reefs, great whites, and all that

Seriously, welcome to the forum. In our enthusiasm to answer questions posed to us by newcomers, we sometimes forget our manners and fail to say 'hello'.
... We understand RC does not permit Orthodox Christians to receive Communion unless there are special circumstances (grave illness, etc) which obviously do not apply in our case. Would that also be the case with UGCC ...
From the Code of Canon Law of the Eastern Churches (CCEO):
Canon 671
3. Likewise Catholic ministers licitly administer the sacraments of penance, the Eucharist and anointing of the sick to Christian faithful of Eastern Churches, who do not have full communion with the Catholic Church, if they ask for them on their own and are properly disposed.
The Code of the Latin (or Roman) Church (CCO) provides similarly:
Canon 844
�3 Catholic ministers may lawfully administer the sacraments of penance, the Eucharist and anointing of the sick to members of the Eastern Churches not in full communion with the Catholic Church, if they spontaneously ask for them and are properly disposed.
As you see, in both instances, the sole requirements are that the Orthodox Christian ask of their own free will to receive such and that they are properly disposed to receive the Mystery. It is not necessary that there be extraordinary circumstances involved.
At the same time, the Catholic Churches do not presume to usurp/interfere in the relationship between Orthodox brethren and their Churches, which ordinarily forbid reception of Mysteries from Catholic clergy. Typically, the caution is voiced (it appears in the backnotes of the missalettes used in many US Latin parishes) that Orthodox Christians consider the discipline or directives of their own Church in deciding whether or not to receive the Mysteries in a Catholic church. In these circumstances, where you have a decided commitment to enter communion with the UGCC, the issue is obviously moot or soon will be. The decision whether to receive the Mysteries in the UGCC prior to your formal entry into communion is yours to make.
We understand our belonging to Orthodox confession should not be a barrier to our son's baptism as a Greek Catholic. Is that true?
From the Code of Canon Law - Eastern:
Canon 681
5. The infant of non-Catholic Christians is
licitly baptized, if the parents, or one of them or the one who legitimately takes their place, request it and if it is physically or morally impossible to approach their own minister.
As you can see from Section 5, technically, (other than in danger of death), the baby's baptism by an Eastern Catholic priest should be limited to instances where no minister of the parents' faith is available (this particular canon doesn't distinguish between the Orthodox and those of other Christian denominations). However, as you and your wife are anticipating entering communion with the UGCC, it makes eminent sense that your son be baptized in the UGCC.
I suspect that set of mixed circumstances you describe (
i.e., you seeking his baptism possibly before the two of you enter communion) is at the heart of another issue that you raised.
Reaffirmation of Faith by the parents
... as we understand it us, parents and the Godparents (mixture of Catholics and non-Catholics) are required to go through the reaffirmation of Faith before baptismal ceremony can take place. Do we understand it correctly, and if so, can non-Catholics go through this ceremony with UGCC?
Canon 681
1. For an infant to be licitly baptized it is necessary that: (1) there is a founded hope that the infant will be educated in the Catholic Church, with due regard for 5; ...
As you see, except in the situation that I previously cited (of a non-Catholic Christian infant baptized by a Catholic priest because of the physical inability to have the baptism performed by a minister of the infant's own Church), the licity of the baptism depends in part on the intent to raise the infant as a Catholic. I think that the priest, in his reference to an affirmation of faith on your part, may be suggesting that you and your wife should commit to your change of communion prior to or simultaneous with your son's baptism.
As to the Godparents, I think he is merely referring to the commitment by the Catholic Godparent to assist in/see to the Catholic upbringing/education of your son. It would make no sense to ask that the non-Catholic (? Orthodox) Godparent affirm his/her belief in a faith (Catholic) to which he/she does not subscribe.
Altenatively, his reference may be to the statements/promises made on the infant's behalf by the parents and Godparents (
e.g., renounciation of Satan).
Finally, the right to have an Orthodox Christian as a Godparent is provided for in the Eastern Code. The only stipulation is that the other Godparent be Catholic.
Canon 685
3. For a just cause, it is permitted to admit the Christian faithful of another Eastern non-Catholic Church to the function of a sponsor, but always at the same time with a Catholic sponsor.
Hope this helps.
Congratulations to you and your wife on the birth of your son

. May God grant him many years, in good health and love of God and his fellow man.
Welcome to both of you in your decision to enter communion with the UGCC and, hopefully, you'll continue to post here. We can always use another Ukrainian (just ask Hritzko

).
Many years,
Neil
