The portion in 1 Corinthians is about liturgies, not just solitary prayer. Only the priest may wear a biretta in church, or, with permission, a zuchetto or mitre when suitable. Even yet, they are occasionally removed. If a guy is found wearing a hat in church, he should be instructed to take it off. But if he refuses, then he has sinned mortally and cannot receive Holy Communion until after confession.
In the early Church, priests would often wear their hair long, covering them with a hat. This was not considered disrespectful, since Christ Himself had done so (see Matthew 9:20).
Priests today are usually given the option of wearing a hat while serving Mass. Although no one will think any less of you if you don't wear one, it is not required.
If you do choose to wear a hat during prayer, there is no rule against doing so. In fact, monks throughout history have used hand-sewn hats as a sign of their vocation. The only people who might find this offensive are those who feel worship must be dressed up fancy, like at a ball game or some other place of entertainment.
Personally, I love hats. They're fun, and let you show off your personality. If you choose to wear one during prayer, I see no reason why anyone should find that offensive.
It is impolite for a guy to wear a hat in church since the Bible states in 1 Corinthians 11:3-16 that a man should not hide his head in church. And disobeying God's commandment shows disdain for his authority. However, this doesn't mean that women cannot wear hats in church. In fact, there are some cultures where girls often wear hats in church. This is because articles of clothing are offered as gifts to God when people pray. So if someone offers a prayer for the person who makes the gift, that person's request is answered through the gift. If the person who receives the gift likes it, they might put it on after praying over it.
In America, there used to be a tradition in some churches for men to wear hats in church. This was done to show respect for the pastor, but also so men would not distract others with their hair or clothes. Today, this practice has fallen out of favor in most churches because most pastors are not required to wear hats and many think it's unprofessional for men to wear hats in church.
However, there are still many churches around that allow men to wear hats in church. If you're interested in wearing a hat in church, ask the pastor first before you buy one. Some pastors may have other suggestions about what types of hats are appropriate for church goers to wear.
When entering a facility or arriving at their destination, men customarily remove their hats. Men are not permitted to wear hats inside a church; however, ladies may wear formal hats. A gentleman will traditionally tip his hat to a lady upon passing. This is not required, but it is appreciated.
When males wear hats within the church, it is considered rude since removing headgear in the church is a symbol of respect to God. Wearing a hat within the church indicates that the wearer has not made an effort to show his or her appreciation for what Jesus has done for us by dying on the cross.
Hats were important tools for working with hair and keeping warm in cold climates like Europe. They are also important accessories for any fashion-conscious man. Wearing a hat in church reminds us all that material wealth is not the most important thing in life. We should work hard and earn money, but only faith in Christ can bring true happiness.
Head coverings are prescribed in several religions as a way of showing reverence toward God. In Islam, men are instructed to cover their heads when praying. In Judaism, a kippa (skullcap) is required during services in many Orthodox congregations.
In Christianity, Catholics are told not to wear hats in church because it shows that we do not have faith in our leaders. Pope Francis has said that he does not like fans being used during meetings or speeches because it is seen as indicating that he is unimportant and can be ignored.
