sancti hodiernus dies solemnis est nobis, a resurrectione Domini quinquagesimus, septem septimanis multiplicatus. Sed computantes septem septimanas, quadraginta novem invenietis: unus additur, ut nobis unitas commendetur. Quid ipse adventus Spiritus sancti, quid egit? Praesentiam suam unde docuit? unde monstravit? Linguis omnium gentium locuti sunt omnes. Erant autem in uno loco centum viginti: per decem duodenarius Apostolorum numerus sacratus mysterio est decuplatus. Quid ergo, singuli in quos venit Spiritus sanctus, singulis linguis omnium gentium sunt locuti, illi alia lingua, et illi alia, et quasi diviserunt inter se linguas omnium gentium? Non sic: sed unusquisque homo, unus homo linguis omnium gentium loquebatur. Loquebatur unus homo linguis omnium gentium: unitas Ecclesiae in linguis omnium gentium. Ecce et hic unitas Ecclesiae catholicae commendatur toto orbe diffusae.
Holy, this present day is solemn for us, the fiftieth from the resurrection of the Lord, made up of seven weeks multiplied. But reckoning seven weeks, you will find forty-nine: one is added, so that unity may be commended to us. What did the very coming of the Holy Spirit do? Whence did He teach His presence? whence did He show it? They all spoke in the tongues of all nations. Now there were in one place a hundred and twenty: the twelvefold number of the Apostles, hallowed by a mystery, was multiplied tenfold by ten. What then, did each one on whom the Holy Spirit came speak in single tongues of all the nations, this one in one tongue and that one in another, and did they as it were divide among themselves the tongues of all nations? Not so: but each man, one man, spoke in the tongues of all nations. One man spoke in the tongues of all nations: the unity of the Church in the tongues of all nations. Behold, here too the unity of the Catholic Church, spread throughout the whole world, is commended.
2. Spiritus sanctus extra Ecclesiam non habetur. Qui ergo habet Spiritum sanctum, in Ecclesia est, quae loquitur omnium linguis. Quicunque praeter hanc Ecclesiam est, non habet Spiritum sanctum. Ideo enim Spiritus sanctus in omnium linguis gentium se demonstrare dignatus est, ut ille se intelligat habere Spiritum sanctum, qui in unitate Ecclesiae continetur, quae linguis omnibus loquitur. Unum corpus, Paulus dicit Apostolus: unum corpus, et unus spiritus (Ephes. IV, 4). Membra nostra attendite. Multis membris constitutum est corpus, et vegetat membra omnia unus spiritus. Ecce humano spiritu, quo sum ego ipse homo, membra omnia colligo: impero membris ut moveantur, intendo oculos ad videndum, aures ad audiendum, linguam ad loquendum, manus ad operandum, pedes ad ambulandum. Officia membrorum dispartita sunt, sed unus spiritus continet omnia. Multa jubentur, multa fiunt: unus jubet, uni servitur. Quod est spiritus noster, id est anima nostra, ad membra nostra; hoc Spiritus sanctus ad membra Christi, ad corpus Christi, quod est Ecclesia. Ideo Apo⟨s⟩tolus, cum corpus unum nominasset, ne intelligeremus mortuum corpus: Unum, inquit, corpus. Sed rogo te, vivit hoc corpus? Vivit. Unde? De uno spiritu. Et unus spiritus. Attendite ergo, fratres, in nostro corpore, et dolete eos qui de Ecclesia praeciduntur. In membris nostris, quamdiu vivimus, cum sani sumus, implent omnia membra officia sua. Si unum membrum dolet alicunde, compatiuntur omnia membra. Tamen quia in corpore est, dolere potest, exspirare non potest. Quid est enim exspirare, nisi spiritum amittere? Jam vero si membrum praecidatur de corpore, numquid sequitur spiritus? Et tamen membrum agnoscitur quid est; digitus est, manus est, brachium est, auris est: praeter corpus habet formam, sed non habet vitam. Sic et homo ab Ecclesia separatus. Quaeris ab illo sacramentum, invenis: quaeris Baptismum, invenis: quaeris symbolum, invenis. Forma est: nisi intus
2. The Holy Spirit is not had outside the Church. Whoever therefore has the Holy Spirit is in the Church, which speaks in the tongues of all. Whoever is outside this Church does not have the Holy Spirit. For this is why the Holy Spirit deigned to show Himself in the tongues of all nations, so that he may understand that he has the Holy Spirit who is held within the unity of the Church, which speaks in all tongues. One body, says Paul the Apostle: one body and one spirit (Eph. 4:4). Consider our members. The body is made up of many members, and one spirit quickens all the members. Behold, by the human spirit by which I myself am a man, I hold all my members together: I command the members to move, I direct the eyes to see, the ears to hear, the tongue to speak, the hands to work, the feet to walk. The functions of the members are divided up, but one spirit holds them all together. Many things are commanded, many things are done: one commands, one is served. What our spirit, that is, our soul, is to our members, that the Holy Spirit is to the members of Christ, to the body of Christ, which is the Church. That is why the Apostle, when he had named one body, lest we should understand a dead body, says: One body. But I ask you, does this body live? It lives. From what? From the one spirit. And one spirit. Consider therefore, brethren, in our own body, and grieve for those who are cut off from the Church. In our members, as long as we live, while we are healthy, all the members fulfil their functions. If one member suffers pain from some cause, all the members suffer with it. Yet because it is in the body, it can suffer pain; it cannot expire. For what is it to expire, but to lose the spirit? But if a member is cut off from the body, does the spirit follow it? And yet the member is recognized for what it is; it is a finger, it is a hand, it is an arm, it is an ear: apart from the body it has form, but it does not have life. So too is a man separated from the Church. You seek the sacrament from him, you find it: you seek Baptism, you find it: you seek the Creed, you find it. It is form: unless within
