Priests

Priests throughout the medieval period wore a white linen alb, a long garment with full-length sleeves that was the mark of all non-monastic clerics. Either flat-soled shoes of tan or black leather were worn on the feet, or decorated shoes of cloth with leather soles.

Over this was worn a long, white linen scarf with decorated and fringed ends - the stola. A smaller maniple (a kind of handkerchief) was attached to the left sleeve. A separate linen collar called an amice was put on and turned down over whatever outer robes were then worn.

The outer garments depended on the type of service to be performed; either a silk poncho-like chasuble or a woollen cope (a kind of cloak with a fastening strap across the upper chest), of various colours aligned with the Church calendar. All of the different garments would be decorated with embroidery, depending largely on the priest's financial status (many were extremely poor).

Despite the wildly inaccurate images in modern popular fiction, brown was never worn by priests and black was onlyworn for funerals.

The priest's hair was supposed to be shorn in the Roman tonsure, but some were fined for not complying.

See links below for images of medieval priests:

Catholic bishops are priests who are appointed to their positions by their superiors. A bishop is normally ordained by other bishops.

Choosing bishops is a matter of seeing what priests have the most experience, skills and knowledge of theology and administration etc., the same as filling a position of importance in any big organisations

A priest can be married. That is another teaching that Catholics teach that isn't a Biblical truth.

1 Timothy 4:1-5 "But the Spirit explicitly says that in later times some will fall away from the faith, paying attention to deceitful spirits and doctrines of demons, by means of the hypocrisy of liars seared in their own conscience as with a branding iron, men who forbid marriage and advocate abstaining from foods which God has created to be gratefully shared in by those who believe and know the truth. For everything created by God is good, and nothing is to be rejected if it is received with gratitude; for it is sanctified by means of the word of God and prayer."

The disciple must give up attachment to home, family, goods (Luke 14:26-33)

When the disciple has learned, the disciple will be like Christ (Luke 6:40)

The vows of marriage mean abandoning the single life, all other devotions and devoting oneself to spouse and family. Similarly, the vows of the Catholic clergy require abandoning all other devotions and committing singular devotion to Christ, God his Father and the ministry. The Catholic ethic for its clergy is that the Church is their bride. Christ knew the weakness of man in that he knew his disciples could not successfully devote their lives to him and at the same to their wives and families. In Mark's gospel, Jesus proclaimed a renewal of moral values based upon a simple invitation: "Follow me." ... and this invitation was also: "Learn and become like me". He bade them to leave their wives and families in order to follow Him. Christ never married because he was committed to his ministry and singularly devoted to his Master, God his Father. In asking his disciples to follow Him, he expected the same of them. It is for this reason that Catholic priests do not marry, the intent being to emulate Christ and Christ's life.

If a landowner gave up his property to the church of Rome, he along with all of his sons will be appointed as Cardinals, yet the Lord's sons cannot marry otherwise, the property and all of the belongings will go to the wive's and son's and not designated to the church.

This is why the priest cannot marry. All that the priest has, belongs to the church.

The levels of priesthood in the Catholic Church are from lowest to highest ranking:

1. parish priest
2. monsignor
   
3. bishop
4. archbishop
5. cardinal
6. Pope

I think" they should be allowed.

380. Catholics call their Priest, "Father," yet Christ said, "Call no man your father upon earth." Matt. XXIII., 9

Your rigid interpretation would forbid your calling an earthly parent father. Yet God Himself, in the commandments, terms one of your parents father, and tells you to honor him as such. Your text means simply, "Call no one your father as if you had no other father with rights over you." That is, you must realize that all paternity is of God, and that you owe your being, and all that you have, including your earthly father, to Him. Nor can any claims of an earthly father avail against our duties to God, our heavenly Father. Meantime, Catholics do not call a Priest "Father" in the same sense as that in which they call God their Father. A Priest, by God's Providence and by the authority of Christ, is a father in the spiritual sense, just as natural parent is a father in an earthly sense. By administering Baptism he gives spiritual life to a soul; he nourishes that life by conferring the Sacraments; he warns, teaches, helps with his advice, corrects, and does all in the spiritual life that an earthly father does in the temporal order. So much so that St. Paul attributes a true paternity to himself, saying, "I admonish you as my dearest children . . . for in Christ Jesus, by the Gospel, I have begotten you." 1 Cor. IV., 14.
We, Catholics, call priests "Father" because they are our spiritual fathers.
