I don't think the early church should be our main go to, but rather the Bible and then if we are confessional, our own confession. It is my opinion that Westminster were better exegetes than many of the early church men (not all). The early church is worth checking on, but as others have mentioned they had A LOT of errors too. One of the biggest ones in this realm was the fact that they purposely tried to get themselves killed. This is likely because they struggled with the same works righteousness errors that many still do today and wanted to prove their faithfulness. I believe there were church leaders during that time period that had to actively discourage this seeking of death (and more than once).
