THIS IS JUST THE TIP OF IT!!...

"Circumcision is based on men’s domination of women. By this procedure, the child is separated from his mother who does not have any authority on him any longer. This harms the child, for at this stage he needs his mother most and she cannot defend him, in spite of the fact that they are attached to one another at this early age. The knife that is pointed to the child is in fact pointed to the heart and soul of the mother. Circumcision is actually an injury to the mother; it is humiliating to her since it implies that ‘Your authority over males is limited; moreover, this child belongs to the male community.’ In this manner, the relationship between man and woman is disturbed and similarly the relationship between mother and child. The child’s separation from the mother is a preparation for his separation from her when he is recruited by the army." (Aldeeb Abu-Sahlieh, 2000)                 That is why some scholars of Judaism doubt the historical origin of the events that took place in the Old Testament. Abu-Sahlieh said that circumcision goes back further than the Old Testament because historical documents were found that proved that circumcision was a procedure carried out in Ancient Syria in the 28th century B.C. and in Ancient Egypt in the 23rd century B.C. In the latter, it was not carried out on all Egyptians but only on the priests. This is proved by the Roman Emperor Hadrian, who forbid this procedure on everyone in the 2nd century A.D,, but he exempted the Egyptian priests.

The Jews used circumcision politically over the years. It was a procedure that was carried out on a relative basis and not done on everyone. Historians state that this procedure was not obligatory to Jews except after their return from exile in the 6th century B.C. A group of Jews made an agreement with surrounding nations in the 2nd century B.C. They stopped observing circumcision, and hid the signs of the procedure by pulling down the skin of the penis to cover its head. They could do so because in ancient times circumcision did not include a complete amputation of the prepuce, as is the case now. It was the outer layer that was cut only. The anti-circumcision trend appeared again in the 2nd century A.D. The rabbis, though, created a new way of circumcision by amputating the two layers of the prepuce as a counter reaction to the mentioned trend. Moreover, in 1842, a group of German Jews questioned the obligatory imposition of circumcision; but they retreated under pressure of conservative Jewish clergy. 

Circumcision Was in Egypt Before Hebrews

Also, as shown on left, the procedure that was practiced in ancient times is nowhere near as intrusive as it is today, i.e. the very rim of the prepuce being cut, versus the full prepuce being removed in today's procedures. The ancient Jews understood the procedure to be symbolic, not an actual surgical procedure, ergo they did something symbolic and not a fully invasive surgical removal which could lead to tremendous complications, to the point of losing one's life or being horribly disfigured.  Furthermore, there are countless passages in the same Old Testament, predating the story of the Abraham circumcision that commands all Jews to never harm the body, in fact it is in no less than 3 of the 10 commandments .   Milah: Symbolic Circumcision of Covenant
The original Biblical circumcision of Abraham's time was a relatively minor ritual circumcision procedure in which only the redundant end of the foreskin extending beyond the tip of the glans was removed. This was called "Milah". It is from this term that the Jewish Religious Covenant circumcision ritual Bris Milah or Brith Milah got its name.    This type circumcision continued throughout the ages and during the time of Christ. The circumcision of Christ would have been this type circumcision as referred to in the bible. Indeed, biblical reference to circumcision is strictly this form of circumcision. It continued into the New Testament. It has been argued that Michelangelo's David should show David as Circumcised. Interestingly, Michelangelo presented David precisely as he should have appeared following an infant "Milah" circumcision. His glans is essentially covered with only the tip of the glans showing.
Changes to the Ritual Circumcision Procedure:
No other feature was added to the religious ritual until about 140 AD when a second step to the ritual circumcision procedure was introduced.
Periah: The laying bare of the glans
After performing "milah", the cutting back of the end of the infant's foreskin, a second step, periah was then performed. Periah consists of tearing and stripping back the remaining inner mucosal lining of the foreskin from the glans and then, by use of a sharp finger nail or implement, removing all of the inner mucosal tissue, including the excising and removal of the frenulum from the underside of the glans. The objective was to insure that no part of the remaining penile skin would rest against the glans corona. If any shreds of the mucosal foreskin tissue remained, or rejoined to the underside of the glans, the child was to be re-circumcised.  
 By introducing the painful and debilitating "Periah" they would obliterate the foreskin completely such that proper circumcised Jew could not disguise "the seal of the covenant". From this point in Jewish history, the male's glans is directly affected by the circumcision procedure, and the denuded glans and traumatized infant will heal with considerable nerve damage and loss of sensitivity. Again, it is important to note that this is not the Covenant circumcision of Abraham defined in the Bible.   Metzitzeh: (Mezzizza/Mizizah) The sucking of blood from the wound.
During the Talmudic period (500-625 A.D.), a third step was added to the Orthodox circumcision ritual. It was not universally adopted by all Jewish groups, but became a practice of the more Orthodox groups. This third step was called "Metzitzah". During "Metzitzah", the mohel takes the now badly bleeding penis into his mouth and sucks the blood from the wounded pant. This was most probably adopted to collapse the major blood vessels to stem bleeding and to extract any induced bacteria from the wound and blood system. In effect, it often introduced infection, such as tuberculosis and venereal diseases, with very serious and tragic consequence, as reported throughout history. More modern day mohels use a glass tube placed over the infant's penis for suction of the blood when performing metzitzah. In many Jewish ritual circumcisions this step of Metzitzah has been eliminated.     Routine Infant Circumcision was introduced during the late 1800's and throughout the 1900's on the pretext that it offered health and hygiene benefits, would stop the habit of masturbation, and proffered an endless list of presumed cures for a variety of ailments and diseases. As mother's opted to use physicians to give birth in hospitals or clinics, rather than using a midwife for home birth, the practice of routine circumcision of male infants blossomed and became nearly universal.
