Pope Francis condemns gender theory for the third time during his visit in Italy.

According to the Life Site, the 78-year old Pope Francis speaks on Sunday about the "ideological colonization" of families he has seen throughout Europe and the West.

"Gender theory is an error of the human mind that leads to so much confusion, so the family is under attack," he said.

Pope Francis had previously lamented during the in-flight interview returning from Manila in the Philippines on January 19, where he said that imposing the homosexual agenda is a form of "ideological colonization" and he even compared it to a Nazi propaganda machine.

The pontiff explained about the "ideological colonization" by giving an example, he says that there is a poor community where a minister of education could loan for building schools as long as the said school will use a book that taught gender theory.

"This is ideological colonization, it colonizes the people with an idea that wants to change a mentality or a structure," Pope Francis explained. "[It] is not new, the dictators of the last century did the same, they came with their own doctrine," he added.

Meanwhile, during his visit to Naples, Italy, Pope Francis accepts a pizza while riding in the Popemobile, cite ABC News.

It was recently reported that Pope Francis would like to go out one day to eat a pizza in a pizzeria, and the employees of Pizzeria Don Ernesto in Naples Italy cooked a pizza for him.

The employees heard that the pontiff likes to eat pizza so they prepare a white and yellow pizza with a buffalo mozzarella and yellow cherry tomatoes.

The co-owner Enzo Cacialli of the Pizzeria personally delivered the pizza to the Holy Father while Pope Francis was riding in the Popemobile.
