Verdict
It is not in Seraphim of Sarov's work
A condemnation of the Old Believer rite that first appears in the 1863 life (Elagin), written by a censor; the episode of the four Old Believers had been expanded in the 1844 life. Mikhail Novoselov held that Seraphim's polemic with the priestless Old Believers of Nizhny Novgorod became anti-ritual under the pen of synodal censors; the question remains open.
