Pretty well. In an Ars Magica game I GM'ed, the covenant was visited by a woman who had recently lost her husband. Having only heard rumors of wizardly powers, she sought out the covenent to bring him back to life - not knowing that such a thing was impossible. They had several dealings with her where they, these magi who probably would never have a normal relationship, got to hear about how much she loved her husband.
Finally, they had to rescue her from a Diabolist sect that promised her that, yes, they could raise her husband from the dead. Or, rather, incarnate a demon in his form and send it out into the world with her. They rescued her, and she finally believed them.
