Why does a Catholic priests where green?

Answer 1

Green robes are worn during Ordinary Time (the periods after Epiphany and Pentecost) and symbolize spiritual life and growth.

Those mantels are called chasubles, not robes, and come from the togas the Roman nobles used to wear.

Answer 2

They wear green for most of the year because it indicates that we are in ordinary time, meaning that we aren't in a significant celebration or time of preparation. There is also purple worn during Lent and Advent (pink during 3rd week of Advent), White worn during Easter and Christmas season, and red for Pentecost/ for the martyrs.

Answer 3

The pope wears green vestments, as do all priests and bishops, when the Church is in Ordinary Time. In other words, when not in the Advent, Christmas, Lent or Easter seasons.

Answer 4

The priest does not wear green, he wears red on Palm Sunday. Red is worn on martyr feasts and Good Friday and Palm Sunday (Jesus Passion), the color of blood.
