181 Every commitment inspired by the Church’s social doctrine is “derived from charity, which according to the teaching of Jesus is the synthesis of the entire Law (cf. Mt 22:36-40)”. This means acknowledging that “love, overflowing with small gestures of mutual care, is also civic and political, and it makes itself felt in every action that seeks to build a better world”. For this reason, charity finds expression not only in close and intimate relationships but also in “macro-relationships: social, economic and political”.
