Marching as to war With the cross of Jesus Going on before. Till all the world adore His sacred name. To add to the beauty and festivity of the services, and to signify their special ministries, the clergy and other ministers wear vestments. The clergy may also wear cassock and surplice. Another familiar vestment is the alb, a white tunic with sleeves that covers the body from neck to ankles.
Deacons wear the stole over one shoulder, priests and bishops over both shoulders.
The deacon's corresponding vestment has sleeves and is called a dalmatic. Bishops sometimes wear a special headcovering called a mitre. Stoles, chasubles, and dalmatics, as well as altar coverings, are usually made of rich fabrics. Their color changes with the seasons and holy days of the Church Year. In recognition of the important events in the life of our Lord, his saints, and his church.
