The Dove is showed as a sign of peace in the christian faith.
During Baptism it is showed that a Dove is there holding an olive branch.
The Dove and the olive is not civil peace but peace to the soul.
This first came up with the early christians.
Noah appeared in lots of religous pictures and the Dove showed up in Noah’s Ark.
Early Christians painted lots of pictures of the Dove holding an olive branch
