Final answer:
Communion, significant in Christianity and also known as the Eucharist, is the consumption of bread and wine in remembrance of Jesus Christ's sacrifice, following His example at the Last Supper.
Step-by-step explanation:
Communion, also known as the Eucharist or The Lord's Supper, is one of the most important sacraments in the Christian faith. It was initiated by Christ at the Last Supper, an event documented in the Bible where Jesus shared bread and wine with His apostles, instructing them to "Take, eat; this is my body" and "Drink from it all of you; for this is my blood of the covenant, which is poured out for the forgiveness of sins" (Matthew 26). In this practice, Christians consume bread and wine to remember and honor the sacrifice of Jesus Christ for the sins of humanity. Within the Catholic and Eastern Orthodox churches, this act is associated with the belief in transubstantiation, the idea that the bread and wine literally become the body and blood of Christ. However, many Protestant denominations view Communion as a symbolic reminder of Christ's sacrifice.
