Strictly, no, I'm afraid.
Officially you're not allowed, but it may vary from church to church - why don't you ask your local priest/vicar. They may be prepared to make an allowance. If it's a long term bond with Christianity you're after, then why don't you ask for a baptisment? Of course, you have to be fully comitted for that.
Only if you have received Baptism, First Confession, and First Holy Communion in a Catholic Church and are in a state of Grace; if you are for some reason unsure if you are able to receive speak to the Pastor before Mass. However, if you are not a Catholic you may not receive Communion.
Yes, you may receive communion if you are not confirmed. However, you should contact a priest in your parish to ask about receiving the Sacrament of Confirmation, especially if you are an adult who is beyond the normal age when Confirmation takes place - the teenage years.
Yes, but only if the Christian has taken the sacrament of the Eucharist, but otherwise, yes.
A matter of minutes if you are confirmed as a roman Catholic. Eastern rite does confirmation either at birth, or after your first communion. I do not know when you receive communion in the eastern rite though.
All Protestants celebrate the Lord's Supper (receive Holy Communion) although the frequency differs from denomination to denomination and church to church. Many Protestants (but not all) participate in "confirmation classes" and are confirmed, while others attend church membership classes and become just members by a public profession of their faith.
Catholic christians who are in a state of grace i.e. they have validly confessed their last mortal sins.
Because one of the reasons for receiving Holy Communion in the Catholic Church is to publicly show your communion with the Catholic Church. Non-Catholics are not in communion with the Catholic Church and therefore cannot receive Holy Communion.
In order to do Communion, you have to take special classes that are around 3 months long and the Pastor/Preacher teaches the class. The classes are about communion, baptisim, the Ten Commandments etc. and once a person passes all the classes and attended all of them, the then go into Confimation which is a big deal. In confirmation the person has to memorize afew things and then they are confirmed and have their first communion. From then on, in the next church services(Sundays), the person can take communion. Before Confirmation even happens, the person cannot do communion.
No, as Orthodox Christians (regardless of age) are only permitted to receive Communion in an Orthodox Church.
Yes, you need to be baptized and Catholic to receive communion. If you are not baptized and are under age 8 you can be baptized with the permission of parent. If you are not baptized and are under 18 you will need to show an understanding of the sacrament before being baptized. If you are not baptized and are an adult you will need to attend classes and then be baptized and confirmed and receive communion at an Easter Vigil Mass.
A five year old is not able to fully comprehend the importance of the sacrament. Some churches will not give communion to those who are not confirmed, which also requires an understanding of communion and of the work of Christ.
From Catholic.com:A non-Catholic may not receive Communion. Actually, not all Catholics may receive Communion. Only those who are in a state of grace can receive the Eucharist. To receive Communion in the Catholic Church is a sign of complete acceptance of Catholic teaching. It is also a sign of complete unity among believers. Unfortunately, Catholic and non-Catholic Christians still do not share such unity. At present, the mutual reception of Communion by Catholics and non-Catholics would not be an honest sign.
Ah, Christians aren't sad at Holy Communion, they are reverent, or should be.
They can, however communion is a thing for people who are Christians/believers ( and they are people with normal sin) to remember Jesus Christ's death on the cross. There is no purpose/reason for somebody who is not a Christian to take communion.
Catholics do not take communion, they receive communion.
