Liturgical Colour : Green or White (Saturday Mass of Our Lady)
Matthew 5 : 33-37
At that time, Jesus said to His disciples, “You have also heard that people were told in the past : Do not break your oath; an oath sworn to the Lord must be kept. But I tell you this : do not take oaths. Do not swear by the heavens, for they are God’s throne; nor by the earth, because it is His footstool; nor by Jerusalem, because it is the city of the great King.”
“Do not even swear by your head, because you cannot make a single hair white of black. Let your ‘Yes’ mean ‘Yes’ and your ‘No’ mean ‘No.’ Anything else you say comes from the evil one.”
