There have been many major Protestant groups and offshoots throughout the years.
In 1517 we have the Lutherans, and then the **Calvinists(Presbyterians) **and **Anabaptists **from that.
And in 1534 we have the Anglican Church, where the Methodists come from in 1784, and the **Pentecostals **come from them in 1901.
And as we look back to the Calvinists, which shot up in 1536, we have the Congretationalists and Baptists that came up around 1607.
From the Baptists we have the Churches of Christ and the Adventists.
Which of these do you find to be the most heretical?
