[Footnote 89: St. Helen discovered the cross on which Christ suffered, and erected a church in Jerusalem, in which it was deposited. “The bishop of that city every year, at the season of the paschal solemnity, exhibits it to be adored by the people, after he himself has first performed his act of profound veneration”. S. Paulinus of Nola, A.D. 430, ep. 11 ad Sever. “In the middle of Lent, the life-giving wood of the venerable cross is usually exposed for adoration”. S. Sophronius patriarch of Jerusalem in 639. (Orat. in Exalt. Crucis). From this custom of the church of Jerusalem probably arose that of the Roman church, in which a crucifix, containing a particle of the true cross, was publicly venerated on good Friday. In the Sacramentary of pope Gelasius (A.D. 402) we read in an account of the ceremonies of this day “The priest comes before the altar, adoring the Lord’s cross and kissing it—all adore the holy cross and communicate”. This ceremony is mentioned also in the Antiphonary of S. Gregory the great and the ancient Ordo Romanus. Flecte genu, lignumque crucis venerabile adora, says Lactantius. See bishop Poynter’s Christianity p. 151. Of the Greeks Leo Allatius relates that “on good-friday, while they accompany as it were Christ himself to the tomb, they lead round through the cities and adore the sculptured body of Christ”. De consensu utriusque Eccl. lib. 5. c. 15. The Syrians also practise this ceremony, as we learn from documents published by Card. Borgia and Nairon. This rite is called the adoration of the cross.
