From the National Catholic Reporter:
Francis…offered the bishops and cardinals what he called a “practical aid” for their work: Twelve pairs of “necessary virtues” they should exhibit—organized as an acrostic for the Latin word for mercy, misericordia.
Pairing fidelity with being a good example, the pope said setting such an example means “avoiding scandals that harm souls and threaten the credibility of our witness”—referencing Jesus’ words in Matthew’s Gospel about having a millstone hung around your neck should you lead someone to sin.
Pairing charity and truth, Francis said those are “inseparable virtues of the Christian existence.”
“Charity without truth becomes ideology of destructive do-gooding and truth without charity becomes bling ‘judicialism,'” said the pope.
Calling for honesty and maturity, the pontiff said honest people “do not act correctly only when they’re being watched by their supervisor.
“The honest person does not have fear of being surprised because they do not ever deceive someone who has trusted them,” he said, adding: “Honesty is the base on which all other qualities rest.”
“Maturity is the search to reach harmony between our physical, psychological and spiritual abilities,” said Francis. “It is the goal and outcome of a never-ending process of growth at does not depend on our age.”
The pope also asked his coworkers to be fearless, and always in a state of readiness.
“To be fearless means never letting yourself be afraid in the face of difficulty—like Daniel in the den of lions, or David before Goliath, it means acting with audacity and determination and without luke-warmness ‘as a good soldier,'” he said.
“It means knowing to take the first step without hesitating, like Abraham and Mary,” he continued.
“Readiness is knowing to act with freedom and agility without attaching yourself to things that pass,” said Francis.
“To be ready means to say being always on the journey, without ever being burdened by the accumulation of needless things and getting caught up in our own projects and without becoming dominated by ambition,” he said.
Francis’ last two virtues were reliability and sobriety.
“The reliable person knows to maintain their commitments with seriousness and responsibility when they are being observed, but above all when they find themselves alone,” said the pontiff. “They radiate a sense of tranquility because they never betray a trust that is given to them.”
“Sobriety… is the capability to renounce the superfluous and to resist the dominant consumerist logic,” he continued.
“Sobriety is to look at the world with the eyes of God and with the gaze of the poor and on the part of the poor,” said the pope. “Sobriety is a style of life which points to the primacy of others as a hierarchical principle and is shown in a life of concern and service towards others.”
Closing his speech, Francis told the curia that mercy is not merely a “passing sentiment” but “the synthesis of the Good News.”
Mercy, he said, is “the choice of whoever wants to have the sentiments of the heart of Jesus, whoever wants to seriously follow the Lord who asks us: ‘Be merciful as your father is merciful.'”
Quoting the Italian theologian and Fr. Ermes Ronchi, the pope continued: “Mercy is a scandal for justice, a folly for intelligence, consolation for us debtors. The debt for being alive, the debt for being loved is only paid with mercy.”
“May mercy guide our steps, inspire our reforms, illuminate our decisions,” asked Francis. “May it be the supporting column of our works. May it teach us when we must go forward and when we must make a step backwards.”
“May it make us able to understand the smallness of our actions in God’s great project of salvation and in the majesty and mystery of his work,” he continued.

 McElwee, Joshua J., “Francis exhorts Vatican prelates to be more mature, recognize ‘smallness’ of work,” National Catholic Reporter (online edition), December 21, 2015. Found at: http://ncronline.org/news/vatican/francis-exhorts-vatican-prelates-be-more-mature-recognize-smallness-work (last assessed Dec. 23, 2015).
In a personal correspondence with the article’s author, Mr. McElwee indicated that the original Italian word used by the pontiff was ‘sobrieta’ — literally in English, sobriety. While one could translate it as ‘moderation,’ McElwee felt that the pope’s intent fairly clearly lined up with the literal English word. In translation, Mr. McElwee is correct; however, contextually ‘moderation’ and ‘temperance’ will likely be understood by tarot enthusiasts more amicably. As part of Pope Françis’s homily, he elucidated thus: “Sobriety–the last virtue on this list, but not because it is least important–is the ability to renounce what is superfluous and to resist the dominant consumerist mentality. Sobriety is prudence, simplicity, straightforwardness, balance and temperance. Sobriety is seeing the world through God’s eyes and from the side of the poor. Sobriety is a style of life which points to the primacy of others as a hierarchical principle and is shown in a life of concern and service towards others. The sober person is consistent and straightforward in all things, because he or she can reduce, recover, recycle, repair, and live a life of moderation.”
