The Church's deepest nature is expressed in her three-fold responsibility: of proclaiming the word of God (kerygma-martyria), celebrating the sacraments (leitourgia), and exercising the ministry of charity (diakonia).
Kerygma: to preach
Leitourgia: to praise
Diakonia: to bless
Referring to the motto of the Dominican Order as the expression of the Church's deepest nature, on top of that "In Truth, Peace" message for the World Day of Peace. I knew I liked this guy.
