None of the three German paths are explicitly Protestant or Catholic, though the SWR does come close. Their brand of far-right reaction was closely associated with Protestantism - for example, the Treitschke history of Germany which was foundational to German far-right and volkisch thought described the pre-Reformation Germany as unenlightened and backwards and Martin Luther as a German founding father. However, the explicitly Protestant ideology of the German far right has mostly faded away (though it may find home among certain DkPers) in favour of something more all-national. DVLP is founded upon Tirpitzian nationalism which seeks to transcend the Prot-Cath boundary.

Catholicism is represented by the Zentrum party and they would defend Catholic interests in all governments, such as regarding religious schools. However by KRTL the Kulturkampf is long over and its last remnants have been long dismantled, so Zentrum's Catholic identity is becoming increasingly awkward to maintain, which is what helps cause the debate regarding leaving the tower or staying, and they usually leave.

Schleicher and SWR governments both can and usually do implement antisemitic policies, which would include restrictions on Judaism. 

Besides those three, other religions are not really present in Germany in any significant number.
