I am reading a very informative book on Jehovah's Witnesses and their beliefs on first century Christianity. The writer goes on to say that there was no such thing as first century Christianity and it only started to take off in the second century onwards. This book and the writer is very well informed. This is a quote that really stood out to me and serves as a guideline for us all today in my opinion.
The Acts of Paul and Thecla (or Thekla) contains the history of a female convert and associate of Paul.  She eventually became a cult hero, with devotees flocking to her shrines, including the pilgrim Egeria, who wrote an account of her journey in AD 384, of which only a fragment survives. Thecla was revered for centuries, almost as much as Mary, the Mother of God, despite the condemnation of Tertullian, a prominent early Christian authority who exposed the work as a forgery.
