The colors of the liturgy are not random. This is what they mean.With the end of the Easter Season, we go back to Ordinary Time.
Ordinary Time is a specific season in the Church that focuses on the life of Christ during his three years of public ministry. That is why the start of Ordinary Time begins with the Baptism of the Lord, as that is the beginning of Jesus’ public ministry. The Second Sunday of Ordinary Time follows suit, focusing on the Wedding Feast at Cana, also known as Jesus’ first public miracle.
The color for this liturgical season is green, which is most associated with growth. Ordinary Time is then viewed as a time of growing in our knowledge and love of Jesus. It is a time “ordered” to spiritual growth, walking in the footsteps of Jesus’s public life.
