113:5.5

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.
