More like the way the Orthodox broke from the Western Church over whether the Creed should say “who proceeds from the Father and the Son” or simply “who proceeds from the Father”; aka the Filioque.
OH Okay never mind
If the “Son” and the “Spirit” both proceed from the Father, then their relation to the Father is the same, and thus there would be two “Sons” or two “Spirits.” There would be nothing to distinguish the Son and the Spirit. If there is nothing to distinguish and the two, they can’t exist. IOW, it’s impossible.
