Who is a Priest ?
A priest is the one who leads a mass and participates in the Eucharist. The Eucharist is the moment celebrating bread and wine sharing, that Christ lived.
The priest who leads the mass ensures that everything goes well and delivers a moral speech called a homily.
A priest can confess to you, that is, collect your sins. A priest has no right to tell them to someone else but can preach to you.
