Political relationship was the relationship between the Bloc Républicain and the church.
Explanation:
The Republicans regarded the Church as a progressive force objecting to socialist policies. That was because the French intellectuals tried to limit or even bring an end to the participation of the Church in government.
Church-State division is a theological and legal term to describe the constitutional difference in the interaction between religious organisations and the nation state.
This word refers conceptually to the development of a secular government and to the abolition of a fixed, existing relationship between church and state, either with or without the specific clear church-state separation.
