Why do many orthodox pastors grow long hair? I've noticed that many of the orthodox pastors are with long hair. I believe it isn't just because but it has a religious background. What's the reason for that? Is it something wrong with short hair in the religion, if any?
Why do many orthodox pastors grow long hair?
I have noticed this even with Eastern Rite Catholic priests.
Igumen Luke explains it as follows:

Orthodox Christian piety begins in the Holy Tradition of the Old Testament. Our relationship to the Lord God, holiness, worship, and morality was formed in the ancient times of the Bible. At the time of the foundation of the priesthood the Lord gave the following commandments to the priests during periods of mourning, And ye shall not shave your head for the dead [a pagan practice] with a baldness on the top; and they shall not shave their beard... (Lev. 21:5), and to all men in general, Ye shall not make a round cutting of the hair of your head, nor disfigure your beard (Lev. 19:27). The significance of these commandments is to illustrate that the clergy are to devote themselves completely to serving the Lord. Laymen as well are called to a similar service though without the priestly functions. This out ward appearance as a commandment was repeated in the law given to the Nazarene, a razor shall not come upon his head, until the days be fulfilled which he vowed to the Lord: he shall be holy, cherishing the long hair of the head all the days of his vow to the Lord... (Numbers 6:5-6).
The significance of the Nazarene vow was a sign of God's power resting on the person who made it. To cut off the hair meant to cut off God's power as in the example of Samson (see Judges 16:17-19). The strength of these pious observances, transmitted to the New Testament Church, were observed without question till our present times of willfulness and the apostasy resulting from it. Why, one might ask, do those Orthodox clergymen, while rejecting the above pious ordinances about hair, continue to observe the custom of granting various head coverings to clergy, a practice which also has its roots in the ancient ordinances of the Old Testament (cf. Ex. 24:4-6) and the tradition of the early Church (see Fusebius and Epiphanius of Cyprus concerning the miters worn by the Apostles John and James)?
The Apostle Paul himself wore his hair long as we can conclude from the following passage where it is mentioned that &quot;head bands,&quot; and &quot;towels&quot; touched to his body were placed on the sick to heal them. The &quot;head bands&quot; indicate the length of his hair (in accor dance with pious custom) which had to be tied back in order to keep it in place (cf. Acts 19:12). The historian Egezit writes that the Apostle James, the head of the church in Jerusalem, never cut his hair (Christian Reading, Feb. 1898, p.142, [in Russian]).
If the pious practice among clergy and laity in the Christian community was to follow the example of the Old Testament, how then are we to understand the words of Saint Paul to the Corinthians cited earlier (I Cor. 11:14)? Saint Paul in the cited passage is addressing men and woman who are praying (cf. I Cor. 11:3-4). His words in the above passages, as well as in other passages concerning head coverings (cf. I Cor. 11: 4-7), are directed to laymen, not clergy. In other passages Saint Paul makes an obvious distinction between the clerical and lay rank (cf. I Cor. 4:1, I Tim. 4:6, Col. 1:7, and others). He did not oppose the Old Testament ordinance in regard to hair and beards since, as we have noted above, he himself observed it, as did Our Lord Himself, Who is depicted on all occasions with long hair and beard as the Great High Priest of the new Christian priest hood.
In our passage noted previously, Both not even nature itself teach you, that, if a man have long hair, it is a shame unto him? (I Cor. 11:14) Saint Paul uses the Greek word for &quot;hair.&quot; This particular word for hair designates hair as an a ornament (the notion of length being only secondary and suggested), differing from [Gr.] thrix (the anatomical or physical term for hair). Saint Paul's selection of words emphasizes his criticism of laymen wearing their hair in a stylized fashion, which was contrary to pious Jewish and Christian love of modesty. We note the same approach to hair as that of Saint Paul in the 96th canon of the Sixth Ecumenical Council where it states: &quot;Those therefore who adorn and arrange their hair to the detri ment of those who see them, that is by cunningly devised intertwinings, and by this means put a bait in the way of unstable souls.&quot;
In another source, The Eerdmans Bible Dictionary, we read the follow ing concerning the Old Testament practice: &quot;To an extent, hair style was a matter of fashion, at least among the upper classes, who were particularly open to foreign [pagan] influence. Nevertheless, long hair appears to have been the rule among the Hebrews (cf. Ezek. 8:3), both men and women&quot; (cf. Cant 4:1; 7:5). Thus we observe that cropped or stylized hair was the fashion among the pagans and not acceptable, especially among the Christian clergy from most ancient times up to our contemporary break with Holy Tradition. It is interesting to note that the fashion of cropped or stylized hair and shaved beards found its way into the Roman Catholic and Protestant worlds. So important had this pagan custom be come for Roman clergy by the 11th Century that it was listed among the reasons for the Anathema pronounced by Cardinal Humbert on July 15, 1054 against Patriarch Michael in Constantinople which precipitated the Western Church's final falling away from the Orthodox Church: &quot;While wearing beards and long hair you [Eastern Orthodox] reject the bond of brotherhood with the Roman clergy, since they shave and cut their hair.&quot; -Concerning the Tradition of Long Hair Beards


St. Tikhon of Moscow
Custom of wearing long hair and beards is not universal nowadays.
Here is what the St. Tikhon of Moscow has to say on the subject matter:

St. Tikhon and Clerical Appearance
When Patriarch St. Tikhon was Bishop in America early this century, he ordered his clergy to shave and wear Western clerical dress. What does this say of your &quot;traditional&quot; dress?
We have seen only one directive attributed to St. Tikhon on this subject, and it by no means &quot;orders&quot; clergy in America under his jurisdiction to abandon traditional Orthodox dress and grooming. It is also well known that the late Father Georges Florovsky disputed the authenticity of this directive. Whatever the case, St. Tikhon did openly speak of a distinction between the &quot;essentials&quot; and &quot;accidentals&quot; of the Faith, allowing for a number of innovations, including some in clerical appearance. A distinction of the kind made by the Saint is atypical in Orthodoxy, wherein &quot;externals&quot; (matters of apparent accident) are thought to reflect and to be inseparable from an &quot;internal&quot; (or essential) reality. St. Tikhon of course embraced this principle, and his deviation from it merely entailed practical accommodations necessitated by difficulties facing the early Orthodox immigration to America. It is both dishonest and an insult to the Saint's memory that his use of justifiable oikonomia in what was then a relatively new mission is now invoked as a standard of Orthodox practice in a local Church that is more than two centuries old.
