New Testament
According to Christian ideas, "foolishness" included consistent rejection of worldly cares and imitating Christ, who endured mockery and humiliation from the crowd. The spiritual meaning of "foolishness" from the early ages of Christianity was closely related to that of rejection of common social rules of hypocrisy, brutality and quest for power and gains.By the words of Anthony the Great: "Here comes the time, when people will behave like madmen, and if they see anybody who does not behave like that, they will rebel against him and say: 'You are mad', — because he is not like them.""We are fools for Christ's sake, but ye are wise in Christ; we are weak, but ye are strong; ye are honourable, but we are despised." (KJV).And also:Western Christianity
In Western Christianity there have been several saints who lived lives which were rather eccentric and seemingly foolish. Among the earliest of them is St. Nicholas of Trani a young homeless man who died in 1094 AD. He apparently never stopped repeating the phrase 'Kyrie Eleison' and behaved foolishly. Similarly Blessed Peter of Foligno lived in voluntary poverty and was deemed crazy.Other notable lay men who led saintly albeit eccentric lifestyles were Blessed Peter of Trevi,  Teobaldo Roggeri, Benedict Joseph Labre, St. Salaun of Brittany Ludovico Morbioli and Casimiro Barello among others. The key characteristics of foolishness for Christ in Western Christianity are sleeping rough and homelessness, a minimalistic lifestyle with very few if any possessions and a strict dedication to prayer and self-renunciation.
Some ascetics are known as mendicants and are organised into mendicant orders. The most famous example in the Western church is Francis of Assisi, whose order was known for following the teachings of Christ and walking in his footsteps. Thus, upon joining the order, Franciscans gave away all possessions and focused on preaching in the streets to the common man.
Servant of God, Brother Juniper, an early follower of the Franciscan order, was known for taking the doctrine of the Franciscans to the extreme. Whenever anyone asked for any of his possessions, he freely gave them away, including his clothes. He once even cut off the bells from his altar-cloth and gave them to a poor woman. His fellow Franciscans had to watch him closely, and strictly forbade him from giving away his clothes. While such behaviors were embarrassing to his brothers, he was also recognized as a pure example of the Franciscan order and thus esteemed.
"The Little Flowers of Saint Francis of Assisi", which documents the oral traditions of the Franciscans, told several stories of "Brother Juniper". The most famous of these is the story of how Brother Juniper, when he heard a sick brother request a pig's foot as a meal, Brother Juniper took a kitchen knife and ran into the forest, where he saw a herd of swine feeding. There, he quickly cut the foot off of one of the swine and carried it back to the brother, leaving the swine to die. This angered the herdsman, who complained to Saint Francis. Saint Francis confronted Brother Juniper, who joyfully exclaimed, "It is true, sweet father, that I did cut off the swine's foot. I will tell thee the reason. I went out of charity to visit the brother who is sick." Brother Juniper likewise explained to the angry herdsman who, seeing the "charity, simplicity, and humility" (Hudleston, 1953) in Brother Juniper's heart, forgave him and delivered the rest of the pig to the brothers.
