“Whoever listens to you listens to me. Whoever rejects you rejects me. And whoever rejects me rejects the one who sent me.” Luke 10:16
To be truly orthodox or traditional means to be obedient to the Church and the rightly elected Vicar of Christ, the Pope. (that’s what my grandfather always told me)
In denying the just election of a pope, the person would ,in fact, be non-orthodox/non-traditional.
I think it’s a problem of modernity. “I have a problem with a teaching or stance of the church, so I’m going to go back in time to where things started to “change” and I’m going to say everything after that is invalid”. Sounds like most SV’s and SSPXers would enjoy Joseph Smith’s views on the Church. Christianity is not a buffet.
