Add January Matins readings for SanctiM (Monastic 1617)-track saints

Starts the bulk-content pass complementary to the pre-1955 saints pass:
11 of January's 13 SanctiM-track saints authored (2 left unsourced —
their Nocturn 2/3 content is entirely octave homiletic material, no
proper vita text in either track). Most SanctiM files turn out to be
thin rule overrides pointing back at the same Sancti/ text; only
St. Maurus (Monastic-only, no Sancti file) needed direct SanctiM
sourcing, with an original translation for its missing English source.

+        ómnium géntium revelabátur salútem, efficácius se ab ipso cápite per totum mundi corpus
+        effúnderet. Cujus autem natiónis hómines in hac tunc urbe non essent? aut quæ usquam
+        gentes ignorárent quod Roma didicísset?
+
+
+        Hic conculcándæ philosophíæ opiniónes, hic dissolvéndæ erant terrénæ sapiéntiæ vanitátes,
+        hic confutándi dǽmonum cultus, hic ómnium sacrilegiórum impíetas destruénda, ubi
+        diligentíssima superstitióne habebátur colléctum quidquid usquam fúerat vanis erróribus
+        institútum. Ad hanc ergo urbem tu, beatíssime Petre Apóstole, veníre non métuis, et,
+        consórte glóriæ tuæ Paulo Apóstolo, aliárum adhuc ecclesiárum ordinatiónibus occupáto,
+        silvam istam freméntium bestiárum, et turbullentíssimæ profunditátis océanum, constántior

+        When the twelve holy Apostles had received from the Holy Ghost the power to speak all
+        languages, they divided the whole world into districts, which they severally allotted to
+        themselves as fields for their Gospel labours. Then was Peter, the Prince of the Apostles,
+        sent to the capital city of the Roman Empire, that he might cause the light to shine thence
+        throughout the whole body of the civilized nations. At that time what nation was there that
+        had no representative in Rome? When Rome had learnt, what people that did not learn too?
+
+
+        In Rome were the dreams of an unbelieving philosophy to be destroyed, in Rome were the
+        empty utterances of earthly wisdom to be confuted, in Rome was idolatry to be overcome, in
+        Rome profanity to be put down, even in Rome, where the activity of superstition had
+        gathered together from the whole earth every error which it could find. O most blessed
+        Apostle Peter! this was the city to which thou didst not shrink to come. The Apostle Paul,
+        thy comrade in glory, was yet occupied in founding the Churches, and thou didst enter alone
+        into that forest of wild beasts roaring furiously; thou didst commit thyself to that stormy
+        ocean, more boldly than when thou walkest upon the waters to come to Jesus.
+
+
+        Thou hadst already taught them of the circumcision who were converted; thou hadst founded
+        the Church of Antioch, the first that bore the noble name of Christian; thou hadst
+        published the law of the Gospel throughout Pontus, Galatia, Cappadocia, Asia, and
+        Bithynia; and thou didst not fear for the hardness of thy work, nor turn back because of
+        thine old age, but didst boldly set up the trophy of the cross of Christ upon those Roman
+        walls, where the Providence of God had appointed the throne of thine honour, and the
+        glorious scene of thy passion.

+        In illo témpore: Venit Jesus in partes Cæsaréæ Philíppi, et interrogábat discipulos suos,
+        dicens: Quem dicunt hómines esse Fílium hóminis? Et réliqua.
+
+
+        Dóminus a discípulis requírit, quem se hómines esse dícerent; ut adjécit, hóminis fílium.
+        Hæc enim confessiónis tenénda rátio est, ut sicut Dei Fílium, ita et fílium hóminis
+        meminérimus: quia álterum sine áltero nihil spei tríbuit ad salútem. Editis ítaque, quæ
+        diversæ de eo erant, hóminum opiniónibus, quid de se ipse séntiant quærit. Petrus
+        respóndit: Tu es Christus Fílius Dei vivi. Sed Petrus conditiónes propositiónis expénderat.
+        Dóminus enim díxerat: Quem me hómines esse dicunt, fílium hóminis? Et certe fílium hóminis
+        contemplátio córporis præferébat. Sed addéndo, Quem me esse dicunt, significávit, præter
+        id quod in se videbátur, esse áliud sentiéndum: erat enim hóminis fílius. Quod ígitur de se
+        opinándi judícium desiderábat? Non illud arbitrámur, quod de se ipse conféssus est: sed
+        occúltum erat de quo quærebátur, in quod se credéntium fides debébat exténdere.
+
+
+        Et dignum plane conféssio Petri præmium consecúta est, quia Dei Fílium in hómine vidísset.
+        Beátus hic est, qui ultra humánum óculos intendísse et vidísse laudátus est: non id quod ex
+        carne et sánguine erat cóntuens, sed Dei Fílium cæléstis Patris revelatióne conspíciens;
+        dignúsque judicátus, qui quod in Christo Dei esset, primus agnósceret. O in nuncupatióne
+        novi nóminis felix Ecclésiæ fundaméntum, dígnaque ædificatióne illíus petra, quæ inférnas
+        leges, et tártari portas, et ómnia mortis claustra dissólveret! O beátus cæli jánitor,
+        cujus arbítrio claves ætérni áditus tradúntur, cujus terréstre judícium præjudicáta
+        auctóritas sit in cælo!

+        At that time, Jesus came into the quarters of Cesarea Philippi: and he asked his disciples,
+        saying: Whom do men say that the Son of man is? And so on.
+
+
+        The Lord asketh His disciples who men say that He is, and He addeth, He, the Son of Man.
+        Let us ever remember to hold fast this truth of our profession, namely, that the Son of God
+        is the Son of Man also. Were He one and not the other, then were He no Saviour for us. The
+        Lord then, having heard the various opinions of men, asketh, But Who say ye that I am? And
+        Simon Peter answered and said Thou art the Christ, the Son of the living God. Peter had
+        weighed the questions. The Lord had asked, Who do men say that I, the Son of Man, am? That
+        He was Son of Man was sufficiently evident to all who looked upon His Body. But when He
+        spake of His whole Self, and asked, Who do ye say that I am? He showed that the mind had
+        something to grasp beyond That Which was seen, for Son of Man He was manifestly. What
+        judgment did He wish them to give? I think it was not that which He had owned concerning
+        Himself. That something more, which He wished them to own, was a hidden thing, whereunto
+        the faith of them that believed in Him was to reach.
+
+
+        Peter's confession was followed by a proper reward for having seen the Son of God in the
+        Son of Man. Blessed is this holy Apostle, in whose praise it is said that he saw with more
+        than human eyes That Which was unseen, who gazed upon Flesh and Blood, and by the secret
+        revelation of the Heavenly Father recognised the Eternal Son of God; who was the first
+        thought worthy to acknowledge the Divinity of Christ. God bless thee, O Peter, thou who by
+        uttering for the first time the title of Divine honour, didst lay the goodly foundation of
+        the Church! God bless thee, thou worthy rock whereon she is built, for ever triumphant over
+        the infernal powers, the gates of hell, and the bands of death! God bless thee, happy
+        door-keeper of heaven, to whose keeping are given the keys of the everlasting mansions,
+        whose sentences on earth are already confirmed in heaven.
