Peace
Peace
Peace.—The precept of charity also includes a precept of peace, and our Lord commands: “Have peace among yourselves” (Mark, ix. 49). Peace, like joy, has two properties: (a) it should be genuine (i.e., it should be a contentment and agreement based on right), for there is a false peace, of which Christ says: “I am not come to bring peace” (Matt, x. 34), which rests in a good that is only apparent, and which does not exclude great evil and anxiety (Wis., xiv. 22), (b) peace is constant, for, as long as charity remains, there are friendly relations with God and man, and order in the interior of the soul. Perfect tranquility, it is true, is found only in heaven. On earth, disturbances may arise in the lower part of the soul, or from without, but the will continues in the peace of God (II Cor., i. 4).
Reconciliation of a sinner to God is effected through an act of perfect charity: “He who loves Me, will be loved by My Father and I will love him” (John, xiv. 21). (a) Thus, sin is washed away, even before Baptism or absolution, when the sinner makes an act of love of God joined with a desire, at least implicit, of receiving the Sacrament of Baptism or Penance. The act of love is not the cause, but the final disposition introducing justification. (b) The punishment of sin is forgiven, when one makes an act of love, or performs a good deed out of love of God; but the degree of remission corresponds to the fervor of the charity.
Does the precept of peace demand unanimity of judgments?
(a) In matters of greater importance, there should be agreement in judgments; else, there will not be that harmony of wills, desiring the same things and disliking the same things, which constitute peace. In necessary things, therefore, there should be unity of judgments: “I beseech of you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing, and that there be no schisms among you, but that you be perfect in the same mind and in the same judgment” (I Cor., i. 10).
(b) In matters of slight importance, difference of opinion does not remove friendship, for each one thinks that his judgment will better serve the good that is sought alike by all. We find that even very holy men have disagreed on matters of opinion—for example, Paul and Barnabas on the question whether or not Mark should be taken on the second missionary journey (Acts, xv. 37), Jerome and Augustine on the status of Mosaic observances after the death of Christ. Disputes may offend against charity, however, if they become too personal or too heated, as sometimes happens even to minds occupied with heavenly things (e.g., theologians, spiritual writers).
