When I went to church today, I saw a cup of bread in the church. What happened? What day is today?

Eating bread and drinking a cup is a real sacrament of the Christian church, and it is a holy meeting that receives God's life, connects with God and intersects with God. None of this should be discussed here, because it is beyond the scope of reason.

In the church, they just hold a ceremony to let the outside world see that they seem to be no different from Christianity in many forms, thus thinking that they are Christian churches (of course, they are not Christian churches, but subordinate units of the government, pretending to be Christians).
