Pope Francis has appealed for forgiveness for all Christians who buy sex from women, describing it as torture.
Talking is important, but "you can't talk to everyone about everything", he said, and told them to find someone "who is wise, who isn't scared and who knows how to listen" to help them sort through the questions they have. "Let's not confuse the terms". Francis has insisted that young adults - Catholic and not - be integral in the process informing the otherwise all-male, celibate and rather old church hierarchy about the future of the church.
The Pope cited examples of God speaking through young people in the Bible: Samuel, David and Daniel, for example.
Pope Francis has asked society for forgiveness on behalf of Catholic men who exploit prostitutes, which he branded as "torture", "slavery" and a "crime against humanity" that stems from a "sick mentality".
"If a young person has this custom, he should drop it", the pope said, referring to paying for sex.
'This isn't making love.
Nicholas Lopez, a college campus minister from Texas, told Francis that young people today face racism, poverty and gang violence, as well as "unjust immigration laws that threaten to split children from families".
Because of this, "we need you young people, living stones of a Church with a young face, but not using makeup: not artificially rejuvenated, but revived from within", he said, explaining that the goal of the synod is to accompany youth.
Pope Francis, who is the 266th and current Pope of the Catholic Church, has made the fight against human trafficking and modern-day sex slaves a priority since his resumption of office. "It is a sickness of humanity, a sickness of looking at society in a certain way, a crime against humanity", he said, adding that feminism has not been able to deal with the problem.
"This is criminal, a sick mentality", he said. "I think of the disgust these young women must feel when these men make them do anything".
"I celebrate that the youth is fighting against this", he said.
Pope Francis is considered too liberal by many in Poland's church, who still follow the more conservative teachings of Saint John Paul II, the late Polish pope who served from 1978 to 2005.
