1 Peter 1:22
Clementine Vulgate · Berean Standard Bible
animas vestras castificantes in obedientia caritatis, in fraternitatis amore, simplici ex corde invicem diligite attentius :
Since you have purified your souls by obedience to the truth so that you have a genuine love for your brothers, love one another deeply, from a pure heart (note: SBL, NE, and WH from the heart).
