From The Missive:
Our Lord’s first appearance to the Apostles manifests these two elements of the one true Church: Christ stands triumphant amidst this motley crew of failures and the word Peace rings out. Breathing upon them, He then says Receive ye the Holy Ghost, giving them all the real power to forgive sins; that is, to restore a soul to grace and establish peace within it, a power continued in the Church through Confession until the end of the world. And it is noteworthy that the word for breath is the same as when God breathed life into Adam – both these instances deal with a life established by and rooted in God.
Therefore, in this first meeting of the Risen Lord with His Apostles do we see the harmonization of the Church’s doctrine and morality: the belief required in the absolute truth of Christ’s teachings and commandments as indicated in the presence of the risen Lord, the conduct of life demanded from belief in those teaching as indicated by the power to forgive sin, thus the establishing of a complete and perfect order for a plan of true peace.
It should be no wonder then that the response for one who claims belief in Christ must be a true interior assent to all the Church proposes for belief as summed up in the Creed, together with a loving submission to the Church’s lawful moral authority which alone has its origin in Christ. No one has any authority to isolate any teaching of Christ and then say peace can be based upon that alone. (Read more.)
