Yeah, my issue isn't so much that one may choose to engage in debate. My issue is when one claims to be a minister for the gospel yet their whole ministry is only about debating and arguing over doctrines in Christianity that have absolutely 0 bearing on one's salvation. Such as Predestination vs. Freewill or Cessationism vs. Continuationism. Jesus said to go forth and make disciples baptizing them in the name of the Father, Son, and Holy Spirit. He didn't say go forth, debating everyone over things that do not matter in the end.
There are multiple people who call themselves ministers who have websites similar to Peters whose first stated goal is to, basically, debate over things that have nothing to do with one's salvation, meaning that one can believe in predestination or freewill or be a cessationist or not, none of those things have any bearing on whether they hear "Well done my good and faithful servant." or not. The funny thing about all of this is that really, I've only ever noticed it from people who call themselves Reformed or Calvinists.
