He urged that every nation establish a national Christian Church and the different established Churches become an international confederation. His views and talents were regarded favorably. Loyson was elected, by liberal Catholics, in the following October, in 1873, along with Hurtault and Chavard, to the three vacant parishes in Geneva. It was impossible for the bishop to retaliate under Swiss law. In 1874, he introduced reforms in worship and soon had to resign. Identified as one of the Old Catholics, Loyson continued to write and preach and ultimately settled in Paris in 1877 and established as a separate church the Église gallicane, which drew upon the long French tradition of Gallicanism.
