Catholics never take Holy Communion, they may only receive Holy Communion. Catholics receive Holy Communion every chance that they are able to primarily because Holy Communion is the actual Body and Blood of Our Blessed Lord, Jesus Christ, and He commanded that you receive it, or, as He put it, "You have no life in you." (John 6:53). Other religions cannot receive Holy Communion at all, because they are not Catholics, and they don't even believe Our Blessed Lord in St. John's Gospel (chapter six) when He insists that this is indeed His Body and Blood:
John 6:61 Aware that his disciples were grumbling about this, Jesus said to them, “Does this offend you? 62 Then what if you see the Son of Man ascend to where he was before! 63 The Spirit gives life; the flesh counts for nothing. The words I have spoken to you—they are full of the Spirit[a] and life. 64 Yet there are some of you who do not believe.†For Jesus had known from the beginning which of them did not believe and who would betray him.65 He went on to say, “This is why I told you that no one can come to me unless the Father has enabled them. and then the infamous 666: After this many of His disciples drew back and no longer went about with Him.
Catholics do not take communion, they receive communion.
Until they are baptized, they are not Catholics. Only Catholics may receive communion in the Catholic Church.
The Church of England allows Catholics, and I presume others, to receive communion out of a "spirit of Ecumenism." Whilst they allow this, a Catholic should not partake of communion with any "church" which is not in communion with Rome; as to do so, is an explicit consent to the believes and teachings of said "church." Please see the link below for a full explanation as to why it is wrong for Catholics to receive communion in a Church not in communion with Rome.
Only Christians and Catholics do.
Yes, and they use wine at communion.
In the Catholic Church non Catholics may not receive communion without a special dispensation from the Bishop. Catholics in the state of serious sin may not receive communion.
In communion Catholics receive the body and blood of Christ under the form of bread and wine.
Catholics believe that communion bread has been turned into the Body of Christ during the Mass, so that is why they go up to the alter reverently.
Catholics do not TAKE Holy Communion, they may only RECEIVE it from a priest or a licensed Eucharistic Minister.
No because receiving communion in the Catholic Church is not only a sign of love, but a communion of Catholics partaking in this sacrament of our redemption by Christ's death.
Yes, they can.
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.
