Among Christian sects, some believe that God is unique, and all believers share the same Eucharist, so they advocate drinking large cups. Others believe that God is a trinity, and different believers share different communion in different places, so they advocate sharing many small cups.
Specifically, the religious differences between Christian sects are mainly manifested in the following aspects:
1. Composition of the Eucharist: Some sects believe that the Eucharist is composed of the blood and flesh of Jesus, while others believe that the Eucharist is only a symbolic ceremony.
2. Distribution of Eucharist: Some sects believe that all believers should share the same Eucharist, while others believe that different believers share different Eucharists in different places.
3. Etiquette of the Eucharist: Some sects believe that the Eucharist should be carried out in accordance with traditional rituals, and some sects believe that the Eucharist should be appropriately adjusted according to the changes of the times.
In short, the beliefs of various Christian sects are different, and different sects have different interpretations and beliefs. However, these differences do not affect believers' belief in God and worship of the Eucharist.
