Catholic celebrate the eucharist when the body and blood of Christ became consecrated.The priest administered it through reading the memorial.Catholics should receive Christ through the Eucharist.
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.
If you meant the question as written, communion decreased in Russia for two major reasons. One, Russia has a majority of Eastern Orthodox adherents and although they do perform communion, such communion is unrecognized by Catholics which could lead to the perception that communions have declined. Two, under communism, the various Churches were banned and people who were faithful took communion in secret. Many, however, gave up the practice. If you actually meant "communism" instead of "communion", the answer is "perestroika" (economic liberalization) and "glasnost" (personal/social freedoms).
