In the Roman Novus Ordo, on the 14th Sunday in Ordinary Time, the Gospel reading contains these words: "Take up my yoke upon you, and learn of me, for I am meek and humble of heart; and you shall find rest for your souls, for my yoke is easy, and my burden light." Meekness is strength shown gently by the exercise of self control. A milquetoast cannot be meek. The word rendered "easy" is better translated "beneficial:" "My yoke is beneficial, good for you." It is not "easy" in the modern sense of the word. The word in the Gospel is in fact the same Greek word which occurs in the Septuagint text of Psalm 33: "Taste and see that the Lord is good" -- which is the Communion Antiphon for this same Sunday.
Simon of Cyrene finds, in this painting by Sebastiano del Piombo, that the burden is light for him when carried together with Christ.
