Normally we're unaware of the ministry of our angels and of their names. You may call your angel by any name you wish – -Nathaniel is a perfectly good one; The Urantia Book does not give their names since there are many millions of them here lovingly performing various tasks.

Here are a few Urantia Book quotes to add to your understanding of these marvelous and sympathetic helpers of the celestial realms:
The angels develop an abiding affection for their human associates; and you would, if you could only visualize the seraphim, develop a warm affection for them. Divested of material bodies, given spirit forms, you would be very near the angels in many attributes of personality. They share most of your emotions and experience some additional ones. The only emotion actuating you which is somewhat difficult for them to comprehend is the legacy of animal fear that bulks so large in the mental life of the average inhabitant of Urantia. The angels really find it hard to understand why you will so persistently allow your higher intellectual powers, even your religious faith, to be so dominated by fear, so thoroughly demoralized by the thoughtless panic of dread and anxiety.
All seraphim have individual names, but in the records of assignment to world service they are frequently designated by their planetary numbers. At the universe headquarters they are registered by name and number. The destiny guardian of the human subject used in this contactual communication is number 3 of group 17, of company 126, of battalion 4, of unit 384, of legion 6, of host 37, of the 182, 314th seraphic army of Nebadon. The current planetary assignment number of this seraphim on Urantia and to this human subject is 3, 641, 852. (113:2.5)
Angels do not invade the sanctity of the human mind; they do not manipulate the will of mortals; neither do they directly contact with the indwelling Adjusters. The guardian of destiny influences you in every possible manner consistent with the dignity of your personality; under no circumstances do these angels interfere with the free action of the human will. Neither angels nor any other order of universe personality have power or authority to curtail or abridge the prerogatives of human choosing.
Angels are so near you and care so feelingly for you that they figuratively "weep because of your willful intolerance and stubbornness." Seraphim do not shed physical tears; they do not have physical bodies; neither do they possess wings. But they do have spiritual emotions, and they do experience feelings and sentiments of a spiritual nature which are in certain ways comparable to human emotions. (113:5.1)
The seraphim act in your behalf quite independent of your direct appeals; they are executing the mandates of their superiors, and thus they function regardless of your passing whims or changing moods. This does not imply that you may not make their tasks either easier or more difficult, but rather that angels are not directly concerned with your appeals or with your prayers.
In the life of the flesh the intelligence of angels is not directly available to mortal men. They are not overlords or directors; they are simply guardians. The seraphim guard you; they do not seek directly to influence you; you must chart your own course, but these angels then act to make the best possible use of the course you have chosen. They do not (ordinarily) arbitrarily intervene in the routine affairs of human life. But when they receive instructions from their superiors to perform some unusual exploit, you may rest assured that these guardians will find some means of carrying out these mandates. They do not, therefore, intrude into the picture of human drama except in emergencies and then usually on the direct orders of their superiors. They are the beings who are going to follow you for many an age, and they are thus receiving an introduction to their future work and personality association.
Seraphim are able to function as material ministers to human beings under certain circumstances, but their action in this capacity is very rare. They are able, with the assistance of the midway creatures and the physical controllers, to function in a wide range of activities in behalf of human beings, even to make actual contact with mankind, but such occurrences are very unusual. In most instances the circumstances of the material realm proceed unaltered by seraphic action, although occasions have arisen, involving jeopardy to vital links in the chain of human evolution, in which seraphic guardians have acted, and properly, on their own initiative. (113:5.3)
