6 Small wonder, then, that the Catholic Church, in imitation of Christ and in fulfilment of His commandment, relies not merely upon her teaching to hold aloft the torch of charity, but also upon her own widespread example. This has been her course now for nigh on two thousand years, from the early ministrations of her deacons right down to the present time. It is a charity which combines the precepts and practice of mutual love. It holds fast to the twofold aspect of Christ's command to give, and summarizes the whole of the Church's social teaching and activity.
