Ordinary Time begins after the feast of the Baptism of Jesus and ends on the Tuesday before Ash Wednesday. During the Sundays of these weeks the readings are remembering the many aspects surrounding the life of Christ.During this year the gospel of the Sunday is from the Mark the evangelist as is the gospel of the weekdays. There are occasions when the reading are particular to a feast day and are to be found at the end of your weekday missal. There are several commemorations of Saints where the readings are in Ordinary Time of a particular week.
The celebrant of the Eucharist will wear green vestments with the exceptions of Feast days. If a martyr is being commemorated red will be worn by the priest, otherwise white is the choice in the case of all other commemorations.
