93 In order that such a solid and undivided love may abide and increase in our souls day by day, we must accustom ourselves to see Christ Himself in the Church. For it is Christ who lives in His Church, and through her, teaches, governs, and sanctifies; it is Christ also who manifests Himself differently in different members of His society. If the faithful strive to live in a spirit of lively faith, they will not only pay due honor and reverence to the more exalted members of this Mystical Body, especially those who according to Christ's mandate will have to render an account of our souls, but they will take to their hearts those members who are the object of our Savior's special love: the weak, We mean, the wounded, and the sick who are in need of material or spiritual assistance; children whose innocence is so easily exposed to danger in these days, and whose young hearts can be molded as wax; and finally the poor, in helping whom we recognize as it were, through His supreme mercy, the very person of Jesus Christ.
