Miklós Ostffy was present at the Bishop's Election Council on June 27, 1669. He welcomed the new bishop, István Szenczi Fekete, during his church-visiting roundtrip on the August 29, 1669, in Asszonyfa. Ostffy, in 1679, gave shelter in his castle to the persecuted Protestant bishop. In 1680 the castle was completely demolished by the Imperial troops of Vienna. Ostffy fled and hid in the Bakony Mountains, then he was lured to Bratislava with a letter of amnesty and imprisoned. (According to one legend, however, he was wonderfully released from the Vienna scythe house.) Miklós Ostffy died in 1691, but his son Mihály Ostffy (1680-1753) took over his church-building work.
