Summary: Basil's homily on the Forty Martyrs is the earliest datable Cappadocian witness to the
developed cult of the martyrs — the martyrs are "common guardians of the human race," "helpers in prayer," "most
powerful intercessors," and the faithful "take refuge" in them. But read carefully it sits one precise step short of
the strict invocation the later Cappadocian texts reach: the soaring address "O common guardians of the human
race!" is encomiastic apostrophe — vocative praise of what the martyrs are — not a
second-person petition ("O martyrs, intercede for us"), and Basil's one imperative of request, "may your
requests be with the martyrs," is spoken to the living congregation, not to the martyrs. He is therefore the strong
floor of the fourth-century evidence: intercession-belief, vivid and public, with the cult fully in view, just before
the unambiguous direct address arrives in the two Gregories.
Basil preached the Homily on the Forty Martyrs of Sebaste at the shrine of the Forty during their festival, to a crowd gathered at the relics. The Forty were soldiers of the Legio XII Fulminata frozen to death on a lake at Sebaste in Armenia under Licinius (c. 320); their cult was among the most popular in Anatolia, and Basil's homily is its earliest datable testimony. Having narrated the martyrdom, Basil turns to the martyrs' present power for the living:
What would you not do, to find one somewhere to entreat the Lord for you? There are forty, sending up a harmonious prayer. Where two or three are gathered in the name of the Lord, there he is in their midst. But where there are forty, who doubts the presence of God? The one who is afflicted takes refuge in the forty, the one who rejoices runs to them… Here a pious woman is found praying for her children, asking for the return of her husband who is abroad, for the salvation of one who is sick. May your requests be with the martyrs.
Then comes the great apostrophe that gives the homily its place in this debate:
O holy chorus! O sacred company! O unbreakable shield-wall! O common guardians of the human race! Good sharers of our cares, helpers in prayer, most powerful intercessors, stars of the world, flowers of the Churches. The earth did not hide you, but heaven received you; the gates of paradise were opened to you.
The Greek behind the key phrases — koinoi phylakes ("common guardians/keepers"), deēseōs synergoi ("fellow-workers of [our] supplication"), presbeutai dynatōtatoi ("most powerful ambassadors/intercessors") — ascribes to the Forty an active, ongoing intercessory office: they guard "the human race," they assist the prayers of the living, they are humanity's "most powerful" envoys before God. The faithful, on Basil's telling, do not merely believe this in the abstract: the afflicted "take refuge in the forty," and Basil commends bringing one's petitions into the martyrs' company.1
Read through the lens the whole timeline must be read through, Basil sits at a sharply defined point, and the page should neither under- nor over-state it.
What the homily plainly attests is robust intercession-belief, and more: a fully public cult of the martyrs — a shrine, a feast, a crowd, relics, and the conviction that the Forty actively guard and assist the living. That is weighty fourth-century evidence and the earliest firm Cappadocian instance of it.
What the homily stops just short of is invocation in the strict sense — a second-person imperative of petition addressed to the martyrs ("O martyrs, intercede for us"). The grammar of "O holy chorus!… O common guardians… helpers in prayer, most powerful intercessors" is vocative praise: it names what the martyrs are, an encomiastic apostrophe of the kind a panegyrist throws toward any honoured subject, present or absent. The one sentence that does carry an imperative of request — "may your requests be with the martyrs" — is addressed in the second person to the living congregation, urging the people to bring their petitions into the martyrs' company; it is not Basil turning to address the Forty. So the strongest accurate reading is that Basil affirms and urges recourse to the martyrs' intercession and apostrophizes them as humanity's guardians — not quite that he prays to them in the formal sense the next generation will.2
For the development-vs-apostolicity question Basil is best read as the hinge. He shows the cult of the martyrs already public, settled, and theologically articulate by c. 373 — not invented out of nothing in 380. Yet what he documents at that date is intercession-belief lodged in a living cult, with direct address still in the encomiastic register; the unambiguous second-person petition to a saint qua saint arrives a few years later in Gregory of Nazianzus (the address to Cyprian) and, most clearly of all, in Gregory of Nyssa's encomium on Theodore. Basil supplies the soil; the two Gregories supply the unambiguous flower.
The c. 373 date is a scholarly inference rather than a fixed datum: it rests on the homily's festival setting at the Caesarean martyrium and on Basil's episcopate (370–379), and the homily is grouped with his other martyr homilies (on Gordius, Mamas, Julitta), all apparently delivered in the 370s. The Oxford Cult of Saints in Late Antiquity project calls it "the earliest datable testimony to the rise of one of the most popular cults of Anatolia." Notably Basil declines to name the place of martyrdom and stresses the martyrs' heavenly citizenship over rival local claims — several Cappadocian and Pontic sites claimed individual members of the Forty — a rhetorical move that may smooth over a contested cult. The authenticity of the homily (CPG 2863) is not in dispute.3

The standard scholarly translation is Pauline Allen, "Basil of Caesarea," in Johan Leemans et al.

The invocation / intercession-belief distinction is weighed on its own page (assessment: sound). On the analysis here — that "O common guardians of the human race… helpers in prayer, most powerful intercessors" is vocative praise (apostrophe) ascribing an intercessory role, while the one imperative of request ("may your requests be with the martyrs") is addressed to the living — see the Oxford Cult of Saints in Late Antiquity database, record E00718 (trans. E. Rizos; "the one who is afflicted takes refuge in the forty… Let your petitions be with the martyrs"). The strictly second-person petition to a saint arrives in the next Cappadocian generation: Gregory of Nazianzus and, most clearly, Gregory of Nyssa. ↩
