I have been asked to write a post on the wearing of headscarves. The better terminology would be the wearing for head coverings of which a head scarf is one particular form of head covering.
According to St Paul men and women each have an iconic function that is: man is the image and glory of God and woman is the glory of man. This iconic function is seen in the manner of the roles of each, the appearance of each and in the relationships between them. The purpose of the iconic function is to manifest the relationship of God to man and make this relationship tangible in our daily lives. The male iconic image is to portray the governance of God over man and the female is to portray the obedience of man to God. Both govern and both obey since this is the relationship of all with God but between themselves a certain order is maintained that we may participate tangibly with God through such relationships and not merely abstractly with the unseen God. This order is manifest within the different levels of relationship between men and women. Mostly notably within the relationship of marriage where we clearly see elsewhere in St Paul the distinct roles of husband and wife in terms of Christ and the Church. However, there is also a public face in terms of permission to exercise public authority and teaching within the Church, the function of the hierarchy, which is permitted to men but not to women because it is God who governs and teaches us and we do not do these things to each other at a merely human level. Thus the male icon is appropriate for the hierarchy because it portrays the divine but the female icon portraying humanity learns in quietness and remains silent in the congregations. Women can govern and teach in private at home or among other women in a convent because man too shares in the governance and teaching of God to men. A married women is expected to exercise these roles in relation to her children. Women can serve the Church as deaconesses but this is a quiet role for ministry to women and it does not perform the same function as a male deacon in leading the congregation and exercising authority over minor orders.
Head coverings are the principle iconic form in terms of establishing ourselves as icons. This is because the main relationship aspect between God and man is in terms of governance and headship. Thus, the head is covered or uncovered to demonstrate this. Head coverings are asked of women to go with long hair as a free expression of obedience to God. Obedience is not forced of man to God but freely given by man hence long hair in itself, as a natural aspect, is not sufficient but a head covering is asked to be added in addition to show the free submission of man to God. The head covering is not merely for the wearers humility and obedience, it quietly bears testimony before all to lead all to obedience and humility. Because obedience to God is due at all times head coverings are also worn at all times, particularly in the presence of others, even in the home. Head coverings are most important though in relation to God seen when praying and also if prophesying. In these activities men uncover their heads to show the authority of God and also that mankind will reign with God in synergy. Women though remain covered to show the need of our continuing obedience to share one will with God. The symbolism of head covering is also used by male monastics to show their life of obedience, although they at times uncover their heads in recognition of the male iconic role that they also convey. The symbols and actions are also for the angels who also look upon us.
A head covering is supposed to cover the head fully as being completely under obedience to God. Thus, head scarves are appropriately wrapped around the head as are also many eastern forms of head coverings as used in Muslim, Jewish or even Hindu cultures. A small hat on top of the head, particularly one that is decorative, is not as appropriate although better than being without, which in terms of its symbolism is a sign of rebellion against God and of self-will, setting oneself as ruling like God if not done according to the will of God. Just as the relationship between God and man is true in all cultures so too is the requirement of head coverings. The only variation being in the type of material and the cut and shape of the coverings but the use of and minimum extent of the covering is to be applied in all cultures as a uniform aspect of Church culture.
Iconic functions are not merely symbolic as signs to teach of something else but there also establish the appropriate form within which Christ becomes present. Because humanity has form in its material aspect then a particular form is required to ensure the true presence of Christ in an incarnate and tangible manner to reflect the reality of our material condition. The material aspect truly participates in our life and existence and this is confirmed that specific material forms are required for mysteries to be manifest, so that the mystery encompasses both spiritual and material aspects of our existence.
