Their very own New Testament says in 1st Timothy 4:3:
"They forbid people to marry and order them to abstain from certain foods, which God created to be received with thanksgiving by those who believe and who know the truth."
So yes it is COMPLETELY RIDICULOUS AND UNBIBLICAL WHAT THEY ARE DOING!
Yes, I think that the Catholic Church really needs to remove the requirement for priests to take a vow of celibacy. It's a tradition that is long past its due date, and also likely one of the reasons there have been so many sex scandals in the Church. Other religions allow married and sexually active clergy.
A priests ability to his job properly has nothing to do with whether or not he takes a vow of celibacy. Not to mention, you can take a vow of celibacy, but it can be not true. It is not a full-proof way of stopping a priest from being a sexual predator.
Vatican II changed many things about church doctrine in the 60s. For example, The Mass is now spoken and celebrated in a country's native language. Also, the regulations of religious life and priesthood were updated. Thus, if doctrine was changed in the past, there is no reason that it can't change in the future. The notion that celibacy is important because of tradition is not a solid argument.
Especially when you consider all the children that got raped by these "celibate" priests. The church could save millions of dollars it has to spend to silence the victims and hide the offenders. But this won't happen because the Christians are obsessed with sex and what other people do when they are naked, you have but to read the bible to see this obsession. The approach the protestant churches use would be a better idea by letting them marry. Having women priests would be an other good idea. But celibacy goes against human nature, as thousands of priests have proven time and again.
The Catholic Church should not remove the requirement for priests to take a vow to celibacy because it is an important part of religion. If the person does not want to remain married only to God than they could always be part of the church in other ways that are as valuable.
No, I do not believe a religion should change its beliefs based on the current society. When a persons decides to become a priest, he should also understand he will also be giving up his right have sexual relations. This should not come as a surprise. It takes as lot faith and will power to take the vow and only those that can live up to that vow should take the positions.
The Catholic Church should not remove the requirement of celibacy of the priests. I think this is something that really matters to the religion and is a tradition we have followed for years. If the person is truly devoted to just God than it will not be an issue for them.
