Undoing The Sandal

Cui quantae reverentiae humilitatem debeat subdendo manifestat Cujus non sum dignus solvere corrigiam calceamenti. Mos apud veteres fuit ut si quis eam quae sibi competeret accipere uxorem nollet, ille ei calceamentum solveret qui ad hanc sponsus jure propinquitatis veniret. Quid igitur inter homines Christus, nisi sanctae Ecclesiae sponsus apparuit? De quo et idem Joannes dicit: Qui habet sponsam, sponsus est. Sed quia Joannem homines Christum esse putaverunt, quod idem Joannes negat, recte se indignum esse ad solvendam corrigiam ejus calceamenti denuntiat. Ac si aperte dicat: Ego Redemptoris nostri vestigia denudare non valeo, quia sponsi nomen mihi immerito non usurpo. Quod tamen intelligi et aliter potest. Quis enim nesciat quod calceamenta ex mortuis animalibus fiunt? Incarnatus vero Dominus veniens quasi calccatus apparuit, quia in divinitate sua morticina nostrae corruptionis assumpsit. Unde etiam per Prophetam dicit: In Idumaeam extendam calceamentum meum. Per Idumaeam quippe gentilitas, per calceamentum vero assumpta mortalitas designatur. In Idumaeam ergo Dominus calceamentum suum se extendere asserit, quia dum per carnem gentibus innotuit, quasi calceata ad nos divinitas venit. Sed hujus incarnationis mysterium humanus oculus penetrare non sufficit. Investigari etenim nullatenus potest quomodo corporatur Verbum, quomodo summus et vivificator spiritus intra uterum matris animatur, quomodo is qui initium non habet, et existit et concipitur. Corrigia ergo calceamenti est ligatura mysterii. Joannes itaque solvere corrigiam calceamenti ejus non valet, quia incarnationis ejus mysterium nec ipse investigare sufficit, qui hanc per prophetiae spiritum agnovit. Quid est ergo dicere: Non sum dignus solvere corrigiam calceamenti ejus, nisi aperte et humiliter suam ignorantiam profiteri? Ac si patenter dicat: Quid mirum si ille mihi praelatus est, quem post me quidem natum considero, sed nativitatis ejus mysterium non apprehendo? Ecce Joannes, prophetiae spiritu impletus, mira scientia emicat et tamen illud de se insinuat quod ignorat.

John the Baptist reveals how great was the humility and reverence he owed to Christ by saying, 'I am not worthy to undo the strap of His sandal.' 1 It was the custom of those of old that if someone were unwilling to take the wife he should have done, he who should have come to her as bridegroom by right of relationship would undo his sandal. 2 How, then, was Christ among men, but that He appeared as the bridegroom of the holy Church? The same John says of Him, 'He who has the bride is the bridegroom.' 3 Since men thought John was the Christ, which John denied, he was right to proclaim his unworthiness to undo the strap of Christ's sandal. As if he were openly saying, 'I am not able to lay bare the footsteps of our Redeemer, because I do not unrightfully usurp for myself the name of bridegroom.' But this can also be understood in another way. Who does not know that sandals are made from dead animals? Our Lord incarnated appeared as if in sandals because in His Divinity He took up the dead flesh of our corruption. So He says through the prophet: 'Over Edom I shall put forth my sandal.' 4 Edom is the Gentiles, and the sandal the mortality He assumed. The Lord asserts that He puts forth His sandal over Edom because when He became known through the flesh to the Gentiles it was as if Divinity came to us shod in sandals. But the human eye is not sufficient for perceiving the mystery of Christ's incarnation. There is no way we can discover how the Word took up a body, how the great and life-giving Spirit came to life in His mother's womb, and how He who has no beginning both is and is conceived. Therefore the sandal strap is the bond of a mystery. John cannot undo the strap of His sandal because even He is not able to understand the mystery of His incarnation, he who through the spirit of prophecy knew of it. What, therefore, does it mean to say, 'I am not worthy to undo the strap of His sandal,' but he openly and humbly confesses his own ignorance? As if he clearly said, 'Why is it a wonder if He has precedence over me? I see He was born after me, but I do not understand the mystery of His birth.' Behold John who was filled with the spirit of prophecy, and who shone with wondrous knowledge, and yet he implies that there is something he does not understand.
