Holy orders is a special sacrament to which the receiver is welcomed into the church as a priest or bishop;
the symbols for holy orders are Laying of the hands and chrism oil.
Priests lay face first on the ground to give their dedication to God.
Also before you are priest you are a decon. So you start off as a deacon and stay like that for a few years and
then you become a priest and later on you CAN choose to become a bishop.If you do choose to become a bishop thenyou help control the diocese or you can simply stay a priest...easy as that.
