Sort of. As he says:
He added that in his view the modern tradition of Halloween had been conceived in a "heathen, contemporary world", as a counterbalance to the Catholic feast of All Souls' Day.
Bear in mind that pumpkins and dressing up as witches etc will be, in Czechy, an American cultural import. And in the previous quote from him:
"Leaving the rectory on Sunday evening, I saw numerous symbols of the satanic feast of 'Halloween' placed in front of our sacred grounds," he wrote.
"I acted according to my faith and duty to be a father and protector of the children entrusted to me and removed these symbols," said Father Smejkal, parish priest at the Roman Catholic Church of St John the Baptist.
I wonder if the quotes around 'Halloween' indicate that he was using the English word. Maybe there is a Czech word, but clearly in his mind, there is an opposition between the Christian feast of All Saints Day and Halloween.
The really disturbing bit is that in his mind the local children have been "entrusted to" him.
