Jesus has manifested His divinity by healing both souls and bodies, St. Peter Nolasco, impelled by this example of divine charity and by a heavenly inspiration (Collect) of which St. Raymund of Pennafort was the instrument, spent all the money he possessed (Gospel) in delivering Christians from the captivity in which their bodies languished among the infidels and their souls were exposed to great dangers.
The Order of our Lady of Ransom, founded with this object, shows how the Kingship of Jesus extends to both the natural and supernatural worlds. By a special vow the religious bound themselves to become prisoners of the pagans, if necessary for the deliverance of their brethren in Christ (Epistle). He died in 1256, and was buried with his cuirass and sword.
Justus ut palma florebit: sicut cedrus Libani multiplicabitur: plantatus in domo Domini: in atriis domus Dei nostri. * Bonum est confiteri Domino: et psallere nomini tuo, Altissime.
The just shall flourish like the palm-tree: he shall grow up like the cedar of Libanus: planted in the house of the Lord, in the courts of the house of our God.
(Psalm 91:13-14,2 from the Introit of Mass)
Deus, qui in tuae caritátis exémplum ad fidélium redemptiónem sanctum Petrum Ecclésiam tuam nova prole foecundáre divínitus docuísti: ipsíus nobis intercessióne concéde; a peccáti servitúte solútis, in coelésti pátria perpétua libertáte gaudére.
O God, who, for an example of Thy charity, didst divinely teach holy Peter to render Thy Church fruitful in a new order for the ransom of the faithful; grant us, through his intercession, that being loosed from the bonds of our sins, we may enjoy perpetual liberty in our heavenly home.
