“Notice how he claims he was admitted to the Catholic Church around Easter of 2002, but then he claims to be a Catholic in 2001.”
Nice sleuthing, but to no effect. All this means is that he started undertaking his inquiry class (or RCIA program) in 2001, and was brought into full membership in the Church the following Easter. This schedule is typical. Baptized converts are received formally into the Church, and the unbaptized are baptize, both during the Easter vigil.
The author suggests that he "poured" over Polycarp.
It makes it hard to view this as serious writing.
