Sacred Name Cults
Deny the Godhead (trinity), may also be taught to keep the Sabbath, identify in some ways with Oneness groups (Oneness Pentecostals, Jesus Only), Assemblies of Yahweh... and spend most of their time proselyting uninformed people from other Christian groups. They may not identify themselves for some time when trying to challenge you to see their point of view. They can be very mean spirited in their comments and remarks and then sign off with, "In Yahushua's Love."
