Here are some quotes from extra-biblical saints. I hope they contribute to the discussion. I underlined points that were interesting to me.
In like manner we do also hear many brethren in the Church, who possess prophetic gifts, and who through the Spirit speak all kinds of languages, and bring to light for the general benefit the hidden things of men, and declare the mysteries of God. (Irenaeus, c.180)
This is He who places prophets in the Church, instructs teachers, directs tongues, gives powers and healings, does wonderful works, often discrimination of spirits, affords powers of government, suggests counsels, and orders and arranges whatever other gifts there are of charismata; and thus make the Lord’s Church everywhere, and in all, perfected and completed. (Novatian, c.200-c.258)
Let Marcion then exhibit, as gifts of his god, some prophets, such as have not spoken by human sense, but with the Spirit of God, such as have both predicted things to come, and have made manifest the secrets of the heart; let him produce a psalm, a vision, a prayer – only let it be by the Spirit, in an ecstasy, that is, in a rapture, whenever an interpretation of tongues has occurred to him; let him show to me also, that any woman of boastful tongue in his community has ever prophesied from amongst those specially holy sisters of his. Now all these signs (of spiritual gifts) are forthcoming from my side without any difficulty, and they agree, too, with the rules, and the dispensations, and the instructions of the Creator; therefore without doubt the Christ, and the Spirit, and the apostle, belong severally to my God. Here, then, is my frank avowal for any one who cares to require it. (Tertullian, c.207)
He became possessed of a spirit, and suddenly began to rave in a kind of ecstatic trance, and to babble in a jargon, prophesying in a manner contrary to the custom of the Church which had been handed down by tradition from the earliest times. (Eusebius, d.c.339)
This whole phenomenon [of speaking in tongues] is very obscure, but the obscurity is produced by our ignorance of the facts referred to and by their cessation, being such then as used to occur but now no longer take place. And why do they not happen now? Why look now, the cause too of the obscurity hath produced us again another question: namely, why did they then happen, and now do so no more? (John Chrysostom, 344-407)
In the earliest times, “the Holy Ghost fell upon them that believed: and they spake with tongues”, which they had not learned, “as the Spirit gave them utterance”. These were signs adapted to the time. For there behooved to be that betokening of the Holy Spirit in all tongues, to shew that the Gospel of God was to run through all tongues over the whole earth. That thing was done for a betokening, and it passed away. In the laying on of hands now, that persons may receive the Holy Ghost, do we look that they should speak with tongues? Or when he laid the hand on infants, did each one of you look to see whether they would speak with tongues, and, when he saw that they did not speak with tongues, was any of you so strong-minded as to say, These have not received the Holy Ghost; for, had they received, they would speak with tongues as was the case in those times? If then the witness of the presence of the Holy Ghost be not given through these miracles, by what is it given, by what does one get to know that he has received the Holy Ghost? Let him question his own heart. If he love his brother, the Spirit of God dwelleth in him. (Augustine of Hippo, 354-430)
For God hath set same in the Church, first apostles…secondly prophets…thirdly teachers…next mighty works, among which are the healing of diseases… and gifts of either speaking or interpreting divers kinds of tongues. Clearly these are the Church’s agents of ministry and work of whom the body of Christ consists; and God has ordained them. (Hilary of Poitiers, 360)
And another night – God knows, I do not, whether within me or beside me – most words which I heard and could not understand, except at the end of the speech it was represented thus: ‘He who gave his life for you, he it is who speaks within you.’ And thus I awoke, joyful. (Patrick of Ireland, 387–493)
And on a second occasion I saw Him praying within me, and I was as it were, inside my own body , and I heard Him above me—that is, above my inner self. He was praying powerfully with sighs. And in the course of this I was astonished and wondering, and I pondered who it could be who was praying within me. But at the end of the prayer it was revealed to me that it was the Spirit. And so I awoke and remembered the Apostle’s words: “Likewise the Spirit helps us in our weakness; for we know not how to pray as we ought. But the Spirit Himself intercedes for us with sighs too deep for utterance.” And again: “The Lord our advocate intercedes for us.” (Patrick of Ireland, 387–493)
