There is the Crooked Cross, which is a weapon that you get for becoming a Crooked Cross.
You were also able to get a Redoubtable Dame-Harbinger during the election by siding with the Bishop, but the Election is over.
You can get the Secular Missionary during the Feast of the Rose as a companion, if you saved her during a specific quest line. I’m not sure if she counts, though. edited by th8827 on 8/4/2016
Do keep in mind, that while the Crooked-Cross is church related, it’s something you get for helping Hell corrupt the church. Just something to consider, if that’s what you’re looking for.
