Paul, an apostle of Christ Jesus according to the commandment of God our Savior, and Christ Jesus our hope;
Grace, mercy and peace ...  Paul usually concluded his letters with "Grace and peace"; but here the inclusion of "mercy" would seem to be best explained thus, "The nearness of death, the weakness of old age, the ever-increasing dangers which crowded around Paul, seem to have called forth from him deeper expressions of love and tender pity."[12]
