Letter to his brother, Prince Henry (21 Apr 1759)

All Religions are equal and good, if only the people that practice them are honest people; and if Turks and heathens came and wanted to live here in this country, we would build them mosques and churches.

[Alle Religionen sind gleich und gut, wenn nur die Leute, die sie praktizeren, ehrliche Leute sind; und wenn Türken und Heiden kämen und wollten das Lande pöpulieren, so wollen wir ihnen Moscheen und Kirchen bauen.]

Note (1740)
On the question of whether a Catholic should be allowed to be a citizen of a Prussian city.

Religions must all be tolerated and the state has to keep an eye that none of them shall derogate the other, because here everyone must find his salvation in his own way.

[Die Religionen müssen alle toleriert werden und der Fiscal muß nur das Auge darauf haben, dass Keine der Andern abruch tue, denn hier muß ein jeder nach seiner Fasson selig werden.]
