Who was Apollos of Alexandria, what role did he play in the Corinthian congregation, and, not least, what did he teach its members? A close reading of Paul’s First Letter to the Corinthians aims to shed light on these issues. The letter will be compared with other 1^st century Alexandrian literature, such as the Book of Wisdom and treatises of Philo, but also with one of the Nag Hammadi-texts, Eugnostos the Blessed. Surprisingly the latter displays common ground with the speculation on wisdom, God, and epistemology as it is attested especially in 1 Cor 1–4.
