The thing to notice about those quotes is they are from the EARLY church fathers, before the completed canon had been fully distributed among the churches. In the ensuing decades those gifts became increasingly rare. In the oldest of your quotes, Bishop Hilary of Poitiers, if you had quote a little further he also said:
"Verily how rare and hard to attain are such spiritual gifts!"
The LATER church fathers reported that the charismatic gifts had ceased.
John Chrysostom (died 407), commentary on 1 Corinthians 12
This whole place is very obscure; but the obscurity is produced by our ignorance of the facts referred to, and by their cessation, being such as then used to occur, but now no longer take place.
...
Now then after [Paul] in every way had shown her [the Church] to be very exceedingly great, he does so again from another most important head, by a fresh comparison exalting her dignity, and saying thus; “but whether there be prophecies, they shall be done away; whether there be tongues, they shall cease.” For if both these [gifts of prophecy and tongues] were brought in for the sake of the faith; when that is every where sown abroad, the use of these is henceforth superfluous. . . . It is no marvel that prophecies and tongues should be done away.
Augustine (died 430), commentary on 1 John
In the earliest time, “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 the Sign adapted to the time. For there behooved to be that betokening of the Holy Spirit in all tongues, to show 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.
Theodoret (died 466) Commentary on the First Epistle to the Corinthians:
In former times those who accepted the divine preaching and who were baptized for their salvation were given visible signs of the grace of the Holy Spirit at work in them. Some spoke in tongues which they did not know and which nobody had taught them, while others performed miracles or prophesied. The Corinthians also did these things, but they did not use the gifts as they should have done. They were more interested in showing off than in using them for the edification of the church.
It is also interesting to note that the church fathers, speaking immediately after the apostolic age, all confirmed that tongues was human foreign languages. None of them said it was a non-human heavenly language.
