does any catholic here actually believe that is sinful or wrong to take communion at a valid church that is not catholic, i my self being a catholic strongly disagree that taking communion from for example an orthodox church or a church that the sacraments are valid can in any way shape or form be sinful doesn’t even matter if the churches are next door neighbors.if you agree that the sacraments are valid and think it is wrong to take it from one of these particular church’s. well you are saying that it is true the flesh and blood of Jesus Christ and are pretty much saying sorry Jesus because your not in a catholic church i cannot have you…can you see how ridiculous this sounds, teachings like these only bring forth more division in the faith not unity, Jesus said that they all may be one; as thou, Father, art in me, and I in thee, while this sounds like a division!
Well, at the least it is illicit to receive sacraments from anyone but a Catholic minister, per Canon Law.
"Can. 844 §1. Catholic ministers administer the sacraments licitly to Catholic members of the Christian faithful alone, who likewise receive them licitly from Catholic ministers alone, without prejudice to the prescripts of §§2, 3, and 4 of this canon, and ⇒ can. 861, §2.
§2. Whenever necessity requires it or true spiritual advantage suggests it, and provided that danger of error or of indifferentism is avoided, the Christian faithful for whom it is physically or morally impossible to approach a Catholic minister are permitted to receive the sacraments of penance, Eucharist, and anointing of the sick from non-Catholic ministers in whose Churches these sacraments are valid."
We are bound by Catholic Church canon law. And are always obliged to celebrate the sacraments licitly as well as validly where this is possible. Even among Catholic churches, if you know that one celebrates them validly but illicitly (the SSPX in at least some cases, for example), but you have the option of valid AND licit sacraments in another place, you ought to go to the other. We owe no less an obligation to Our Lord who has graciously given us the Sacraments.
Why are the sacraments of the Orthodox valid but not licit? Put it this way. You choose to be a US citizen and are thus bound to obey US law. If I am a visitor in your country I too am subject to it.
Does that mean the citizenships and laws of other countries are somehow inferior or invalid in any way? Not necessarily.
But does it mean that the laws of those other countries equally apply to you or me on US soil? For example, that we can go around acting as if French, German or Japanese law applied in the States instead of US law? No again. Each country has its own laws, and its citizens and tourists are obliged to abide by them. :shrug:
Is a sad fact - some like Vladimir Sergeevich Solovijov believed like you that just can receive communion Catolic or Orthodox. This is bad idea as you can understand from your own church view. You are Catolic, not Orthodox.
But in fact Orthodox church also does not allow communion except to Orthodox or at least in most cases to those who have spoken to priest before hand, knows them to be orthodox, knows their Christian name and knows that they have been confessed in not distant past. Then he will think to communion them if they present themselves. But just someone unknown to show before priest - he may bless this unknown person and move on to communion other one.
