In addition, here are the quotes of the Early Church Fathers,
“[T]hat it is neither possible for us ever to forsake Christ, who suffered for the salvation of such as shall be saved throughout the whole world (the blameless one for sinners), nor to worship any other. For Him indeed, as being the Son of God, we adore; but the martyrs, as disciples and followers of the Lord, we worthily love on account of their extraordinary affection towards their own King and Master, of whom may we also be made companions and fellow disciples! The centurion then, seeing the strife excited by the Jews, placed the body in the midst of the fire, and consumed it. 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.” Martyrdom of Polycarp 17,18 (A.D. 157).
“[Appealing to the three companions of Daniel] Think of me, I beseech you, so that I may achieve with you the same fate of martyrdom.” Hippolytus of Rome, On Daniel, 11:30 (A.D. 204).
“As often as the anniversary comes round, we make offerings for the dead as birthday honours.” Tertullian, The Crown, 3 (A.D. 211).
“Nor is that kind of title to glories in the case of Celerinus, our beloved, an unfamiliar and novel thing. He is advancing in the footsteps of his kindred; he rivals his parents and relations in equal honours of divine condescension. His grandmother, Celerina, was some time since crowned with martyrdom. Moreover, his paternal and maternal uncles, Laurentius and Egnatius, who themselves also were once warring in the camps of the world, but were true and spiritual soldiers of God, casting down the devil by the confession of Christ, merited palms and crowns from the Lord by their illustrious passion. We always offer sacrifices for them, as you remember, as often as we celebrate the passions and days of the martyrs in the annual commemoration. Nor could he, therefore, be degenerate and inferior whom this family dignity and a generous nobility provoked, by domestic examples of virtue and faith. But if in a worldly family it is a matter of heraldry and of praise to be a patrician, of bow much greater praise and honour is it to become of noble rank in the celestial heraldry! I cannot tell whom I should call more blessed,–whether those ancestors, for a posterity so illustrious, or him, for an origin so glorious. So equally between them does the divine condescension flow, and pass to and fro, that, just as the dignity of their offspring brightens their crown, so the sublimity of his ancestry illuminates his glory.” Cyprian, To Clergy and People, Epistle 33(39):3 (A.D. 250).
“I am also of opinion that there were many persons of the same name with John the apostle, who by their love for him, and their admiration and emulation of him, and their desire to be loved by the Lord as he was loved, were induced to embrace also the same designation, just as we find many of the children of the faithful called by the names of Paul and Peter.” Dionysius of Alexandria, Books of Promises, 5 (A.D. 257).
“Then we commemorate also those who have fallen asleep before us, first Patriarchs, Prophets, Apostles, Martyrs, that at their prayers and intercessions God would receive our petition. Then on behalf also of the Holy Fathers and Bishops who have fallen asleep before us, and in a word of all who in past years have fallen asleep among us, believing that it will be a very great benefit to the souls, for whom the supplication is put up, while that holy and most awful sacrifice is set forth.” Cyril of Jerusalem, Catechetical Lectures, 23:9 (A.D. 350).
“Thus might you console us; but what of the flock? Would you first promise the oversight and leadership of yourself, a man under whose wings we all would gladly repose, and for whose words we thirst more eagerly than men suffering from thirst for the purest fountain? Secondly, persuade us that the good shepherd who laid down his life for the sheep has not even now left us; but is present, and tends and guides, and knows his own, and is known of his own, and, though bodily invisible, is spiritually recognized, and defends his flock against the wolves, and allows no one to climb over into the fold as a robber and traitor; to pervert and steal away, by the voice of strangers, souls under the fair guidance of the truth. Aye, I am well assured that his intercession is of more avail now than was his instruction in former days, since he is closer to God, now that he has shaken off his bodily fetters, and freed his mind from the clay which obscured it, and holds intercourse naked with the nakedness of the prime and purest Mind; being promoted, if it be not rash to say so, to the rank and confidence of an angel.” John Chrysostom, On the Death of his Father, Oration 18:4 (A.D. 374).
