Actually Origen had access to vastly more Scripture than we have. Not only did his library, which he later sold to give alms to the poor, contain every book in the canonical New Testament, it also contained several works that almost made it into the canon. And in the case of the Old Testament, Origen authored the Hexapla, the world’s first Parallel Bible, which compared the Septuagint and five distinct Hebrew editions, most of which, like Symacchus, are lost or exist only in untraceable fragments amid the Dead Sea Scrolls.
I would gladly forfeit an actual arm and a leg and become a paraplegic for access to Origen’s library and also a complete collection of his writings and the other Patristic texts he and the Greek fathers had access to.
The Latin fathers up to and including Pope St. Gregory Diologos, who developed Gregorian Chant and the Presanctified Liturgy used in the Eastern Orthodox church, and until 1955, in the Roman Catholic Church, and his immediate successors, also had very good libraries and most of them spoke Greek. Indeed, the Church in Rome used the Greek language exclusively for worship until the reign of Archbishop Victor in the mid 2nd century, who introduced a vernacular liturgy and a vernacular Bible, the Vetus Latina, portions of which you have almost certainly heard, for instance “Gloria in excelsis deo.” The Vulgate translated this as “Gloria in altissimus deo”
Now, the Syriac fathers had a rougher time of it, except for those who also spoke Greek, until the appearance of the Peshitta translation in the fourth century, but after that point, there was a massive amount of translation from Greek into Syriac, so interestingly enough, the Renaissance happened because the Western Europeans, who during the dark ages did lose most of their books, with a monastery being lucky if it had more than a Vulgate Bible, the prerequisite liturgical books, and St. Augustine, obtained Latin translations of Arabic translations of Syriac translations of Aristotle, Plato and the other Greco-Roman philosophers (Archimedes, Euclid, Galen, etc), which were prepared by Syriac Orthodox monks at the Syrian Monastery in Egypt, which still exists but is inhabited by Coptic Orthodox monks, and the Monastery of St. Matthew in the hills above Mosul, Iraq, which miraculously survived ISIS and remains in operation, and some monasteries associated with the Assyrian Church of the East which are sadly long gone.
