No ad hominem. You mentioned Baptism, the sacraments, communion, all are doctrine.
That statement is an ad hominem, because it criticizes *me* instead of my claim.
You mentioned Baptism, the sacraments, communion, all are doctrine.
I agree that baptism, communion (i.e. Eucharist), and the other five sacraments are doctrine. But most Protestants reject the sacramental character of baptism and the Eucharist (treating them as mere symbols). Most Protestants also reject the other five sacraments. And most Protestants also reject the doctrine of the "communion of saints".
