Accordingly, we afterwards took up his bones, as being more precious than the most exquisite jewels, and more purified than gold, and deposited them in a fitting place, whither, being gathered together, as opportunity is allowed us, with joy and rejoicing, the Lord shall grant us to celebrate the anniversary of his martyrdom, both in memory of those who have already finished their course, and for the exercising and preparation of those yet to walk in their steps
Peter of Alexandria Genuine Acts of Peter (260-311ad)
In the meanwhile a spirited body of senators of those who are engaged in the public transport service, seeing what had happened, for they were near the sea, prepared a boat, and suddenly seizing upon the sacred relics, they placed them in it, and scaling the Pharos from behind, by a quarter which has the name of Leucado, they came to the church of the most blessed mother of God, and Ever-Virgin Mary, which, as we began to say, he had constructed in the western quarter, in a suburb, for a cemetery of the martyrs
Athanasius Life of St Anthony par 92 (296-373 ad)
But each of those who received the sheepskin of the blessed Anthony and the garment worn by him guards it as a precious treasure. For even to look on them is as it were to behold Anthony; and he who is clothed in them seems with joy to bear his admonitions.
Basil Letter 49 (329-379 ad)
If I am able to find any relics of martyrs, I pray that I may take part in your earnest endeavour.
Basil Letter 155 (329-379 ad)
If you send the relics of the martyrs home you will do well; as you write that the persecution there is, even now, causing martyrs to the Lord.
Basil Letter 197 par 2 (329-379 ad)
he took up the relics with all becoming reverence, and has aided the brethren in their preservation. These relics do you receive with a joy equivalent to the distress with which their custodians have parted with them and sent them to you

She hurried to the martyrs’ shrines unnoticed. Such visits gave her pleasure, and the more so because she was never recognized.

Jerome Letter 46 par 13 (347-420 ad)

Jerome against the Vigilantius par 5 (347-420 ad)
Are we, therefore guilty of sacrilege when we enter the basilicas of the Apostles? Was the Emperor Constantius I. guilty of sacrilege when he transferred the sacred relics of Andrew, Luke, and Timothy to Constantinople?
Jerome Letter 109 par 1 (347-420 ad)
You tell me that Vigilantius (whose very name Wakeful is a contradiction: he ought rather to be described as Sleepy) has again opened his fetid lips and is pouring forth a torrent of filthy venom upon the relics of the holy martyrs; and that he calls us who cherish them ashmongers and idolaters who pay homage to dead men’s bones. Unhappy wretch! to be wept over by all Christian men,… We, it is true, refuse to worship or adore, I say not the relics of the martyrs, but even the sun and moon, the angels and archangels, the Cherubim and Seraphim and “every name that is named, not only in this world but also in that which is to come.” For we may not “serve the creature rather than the Creator, who is blessed for ever. Still we honour the relics of the martyrs, that we may adore Him whose martyrs they are. We honour the servants that their honour may be reflected upon their Lord
John Chrysostom Homily on St Ignatius par 5 (347-407 ad)
For not the bodies only, but the very sepulchres of the saints have been filled with spiritual grace. For if in the case of Elisha this happened, and a corpse when it touched the sepulchre, burst the bands of death and returned to life again, much rather now, when grace is more abundant, when the energy of the spirit is greater, is it possible that one touching a sepulchre, with faith, should win great power; thence on this account God allowed us the remains of the saints, wishing to lead by them us to the same emulation, and to afford us a kind of haven, and a secure consolation for the evils which are ever overtaking us.
John Cassian Conference 6 ch 1 (360-435 ad)
In this district there lived for a long while monks of the most perfect life and holiness, who were suddenly destroyed by an incursion of Saracen robbers: (3) whose bodies we knew were seized upon with the greatest veneration (4) both by the Bishops of the neighbourhood and by the whole populace of Arabia, and deposited among the relics of the martyrs, so that swarms of people from two towns met, and made terrible war upon each other, and in their struggle actually came to blows for the possession of the holy spoil, while they strove among themselves with pious zeal as to which of them had the better claim to bury them and keep their relics
Augustine Letter 212 (354-430 ad)
how much stronger is their claim on you, who reside in the same country in this earth in which these ladies, for the love of Christ, renounced the distinctions of this world I also ask you to condescend to receive with the same love with which I have offered it my official salutation, and to remember me in your prayers. These ladies carry with them relics of the most blessed and glorious martyr Stephen: your Holiness knows how to give due honour to these, as we have done.
Augustine of Hippo City of God Book 22 ch 8 (354-430 ad)
For even now miracles are wrought in the name of Christ, whether by His sacraments or by the prayers or relics of His saints; but they are not so brilliant and conspicuous as to cause them to be published with such glory as accompanied the former miracles.
Sozomen Ecclesial History Book 3 Ch 14 (375-477 ad)
He (the monk Antony the great) was earnest in conduct, grave in discourse, and with a good memory and accurate attainment in Sacred Writ. He was so beloved by God, that even now many afflicted and possessed people are healed at his tomb.

Likewise also I venerate and honour and salute the relics of the Saints as of those who fought for Christ and who have received grace from him for the healing of diseases and the curing of sicknesses and the casting out of devils, as the Christian Church has received from the holy Apostles and Fathers even down to us to-day.
