Note 37 — Chapter III · THE BARBARIAN INVASIONS.
Reading edition
Even so early as the middle of the fifth century, S. Leo the Great could say to the Roman people, 'Isti (sc. Petrus et Paulus) sunt qui te ad hanc gloriam provexerunt ut gens sancta, populus electus, civitas sacerdotalis et regia, per sacram B. Petri sedem caput orbis effecta latius præsideres religione divina quam dominatione terrena.'—Sermon on the feast of SS. Peter and Paul. (Opp. ap. Migne tom. i. p. 336.)
