You will have to go onto a Presbyterian or Episcopalian website and ask them. This is a Baptist website and Reformed Baptists have never persecuted anyone.
Depends what is included in"persecuted" ........
We had a mixed ethnicity church of 30, singing English & Indian hymns, & needing translation at every service. Around 50 would attend for special meetings. We had 6 baptisms in our final year. We were meeting in a Brethren owned Gospel Hall, which we'd used for 20 years. The trustees decided to sell it, & were pleased that a Grace Baptist group wanted to buy. We knew members of the group & some had worshipped with us, & preached for us. Our Pastor & a missionary working with us had retired moved away. I was 70.
The leader of the group was an American who wanted to set up a church plant. We met with him, & expressed our willingness to continue under his leadership as a Grace Baptist Church.
However
He wanted a church plant, so did not want ANY of existing church folk to continue. We held our final meeting, our 148th church anniversary with a packed church. We continued to meet in homes, but folk went to various local churches.
I tried to join them when they were distributing introductory leaflets. I "wasn't needed." I asked to attend their prayer meeting & was discouraged.
Did the Reformed have a change in heart? Or did they have another reason to stop the bloodshed?
There was relative peace between RC & Lutherans after the "Peace of Augsburg" in 1555. Then all Europe was at war -
the 30-years War after the 1618 "defenestration" incident, until the "Peace of Westphalia" in 1648. Perhaps the Anabaptists &other independent groups were allowed relative peace, not being a military enemy.
But not in England, nor other parts of the British Isles. After the English civil war the monarchy was restored in 1660. Soon 2000 Presbyterian & Independent ministers were expelled from their pulpits, & various legislation put them into prison. Until 1689, when the RC King James 2 fled the country, & the "Toleration Act" allowed some religious liberty, hence the 1689 Baptist Confession. Soon after, James tried to get back, occasioning a vicious war in Ireland that still has repercussions today, & his son Charles (bonnie pPrince Charley) tried again via Scotland in 1745 - which occasioned the "highland clearances."
