What do you mean by pointing at you, pointing at yourself and crossing your fingers?

Protestantism generally does not draw a cross, Catholicism is up and down, and Orthodox Church is up and down.

Put your hands together and pray, of course. In countries where Christianity prevails in Europe and America, it is still popular to cross the index finger and middle finger of one hand, which is a simplified cross. When it is inconvenient to pray formally or to be seen by others. For example, when I lie, I secretly cross my fingers so that others can't see it, which means I'm lying. God don't punish me ~ ~

You can read the Bible, especially the New Testament. Most of the names in it can be used as holy names, but they are actually the names of ancient saints. Such as Joseph Peter, John Matthias, Jacob, etc. This is the name of an ancient Catholic saint. The Orthodox Church has a different understanding of saints than the Catholic Church, so the names of saints are different. Protestantism generally has no holy name. Don't be confused, and then let the experts make jokes.
