The following is found in "UFO Contact from the Pleiades, Vol. 1" of which I have a numbered edition. The Pleiadian cosmonaut, Semjase, is quoted by Eduard "Billy" Meier who made contacts in Switzerland in 1975.

"We, too, are still far removed from perfection and have to evolve constantly, just like yourselves. We are neither superior nor super-human, nor are we missionairies... but we have taken on certain tasks such as, for example, the supervision of developing life in space, particularly human, and to ensure a certain measure of order. In the course of these duties we do here and there approach the denizens of various worlds, select some individuals and instruct them. This we do only when a race is in a stage of higher evolution. Then we explain (and prove) to them that they are not the only thinking beings in the universe."

"And neither is it consistent with the truth that our brothers and sisters come from other parts of space on behalf of a God to bring to the world the long-awaited peace. In no case do we come on behalf of anybody, since creation, by itself confers no obligation (on us). It is a law unto itself, and every form of life must conform with it and become a part of it."

Additional quotes are possibly available should you let me know your interest in them.
