For those complaining about the singing....

The hole church took power gradually by making hymns the only available music, before banning folk songs once they had power. They were so deeply integrated in people's everyday life that they stopped questioning it. Those who did were disposed of.

Now, also remember that the goddess? Who sent her back in time for another chance, did it solely to hear her sing as much as possible. Lippe promised to sing, to spread her song, if she was to be given another chance at protecting her family. By gaining fame, she's also planting her family more firmly in people's heart, gaining the family more allies and sympathy. The family is still careful about showing how much power they have right away, but already they're in a better position than in the past.
