29 The Church, moreover, intervenes directly in behalf of the poor, by setting on foot and maintaining many associations which she knows to be efficient for the relief of poverty. Herein, again, she has always succeeded so well as to have even extorted the praise of her enemies. Such was the ardor of brotherly love among the earliest Christians that numbers of those who were in better circumstances despoiled themselves of their possessions in order to relieve their brethren; whence "neither was there any one needy among them."(24) To the order of deacons, instituted in that very intent, was committed by the Apostles the charge of the daily doles; and the Apostle Paul, though burdened with the solicitude of all the churches, hesitated not to undertake laborious journeys in order to carry the alms of the faithful to the poorer Christians. Tertullian calls these contributions, given voluntarily by Christians in their assemblies, deposits of piety, because, to cite his own words, they were employed "in feeding the needy, in burying them, in support of youths and maidens destitute of means and deprived of their parents, in the care of the aged, and the relief of the shipwrecked."(25)
