One of the customs of this most solemn occasion is to get a taste of Vinegar and Mirrah mixed in little water. Usually one or more small bottles passed around for a little sip. People leave the church without the ordinary kiss of agape, because this was the time of betrayal when the Only Begotten of the Father was betrayed and suffered alone for the sins of all people.
