What are the taboos of Christianity?

Everyone has his own beliefs and religions, among which there are many Christians. So what are the taboos of Christianity? Now let's talk about it in detail:

The main taboos of Christian leaders are:

First, it is forbidden to worship idols other than God. When giving gifts to Christians, avoid having gods of other religions or totems worshipped by other nationalities. To respect Christian faith, don't swear to God, let alone make fun of God Jesus.

Second, avoid food with blood.

Third, don't be disheveled. Non-Christians should wear neat clothes when they enter the church. When they enter, they should take off their hats and keep their voices down when they talk to others. They should not interfere with each other's normal religious activities. Non-Christians on the sidelines should not make any noise when praying or singing poems. However, when everyone stands up, they should stand up with others. If someone offers himself bread or bread, he should refuse.

Fourth, Christians have the habit of fasting. Christianity stipulates that Christians only eat vegetarian dishes and fish every Friday and peaceful nights, and do not eat other meat.

Five, taboo 13th and Friday. If 13 and Friday happen to be the same day, people often stay indoors, so don't disturb them at these times.
