Historical Context
Alexander I led the Roman Church in the early second century, an era for which biographical records are sparse and largely reconstructed from later sources. St. Irenaeus' enumeration of the Roman succession places him fifth from the Apostles, and he is consistently named between Evaristus and Sixtus I.
Modern scholars treat the dating of his pontificate as approximate, offering ranges such as 106–115 (Duchesne) and 109–116 (Lightfoot). His identification as bishop of Rome rests on documents of questionable accuracy composed in the centuries after his repose, so most concrete details of his life are held with caution.
