This sounds less like a complaint on professionalism, and more like a personal beef. Not one reflected by the wider church - you'll find many leaders both in and outside the Catholic church, who communicate regularly, and coordinate their efforts together.
There's a massive corpus of commentary written from ~400-100 AD, nevermind 1500...
