There's this one female saint, who was a Monophysite, I think she was a monastic, unfortunately I can't find her name anymore.
I believe St Martyr Sava the Goth was likely an Arian, and I was told there are a couple other Arian saints as well.
St Isaac of Nineveh was definitely a Nestorian if the texts found in 1983 that are attributed to him are actually his.
But having misconceptions about God is not what itself endangers salvation greatly. After all, I'm pretty sure we all have misconceptions about God, how could we not? However, being aligned with a sect that is in opposition to the Church puts one on the path to eternal damnation. So, somebody who was in the Church but rejects our anathema on Nestorianism, or somebody who belongs to the Church of the East today, or somebody who has analyzed the arguments for and against Nestorianism and has decided to join the Nestorian Church… is walking down the path of destruction.
