VI. Reconciliation between enemies and almsgiving are also Lenten duties
Furthermore, as the Lord says, that “the peacemakers are blessed, because they shall be called sons of God,” let all discords and enmities be laid aside, and let no one think to have a share in the Paschal feast that has neglected to restore brotherly peace. For with the Father on high, he that is not in charity with the brethren, will not be reckoned in the number of His sons. Furthermore, in the distribution of alms and care of the poor, let our Christian fast-times be fat and abound; and let each bestow on the weak and destitute those dainties which he denies himself. Let pains be taken that all may bless God with one mouth, and let him that gives some portion of substance understand that he is a minister of the Divine mercy; for God has placed the cause of the poor in the hand of the liberal man; that the sins which are washed away either by the waters of baptism, or the tears of repentance, may be also blotted out by almsgiving; for the Scripture says, “As water extinguishes fire, so alms extinguishes sin.” Through our Lord Jesus Christ, etc.
