We are called to be "perfected in love'.  God and God's love is perfect and THAT is what we are called to be perfected in.  We're not perfect, and on this earth we will not be.  But as Jesus taught and demonstrated at every turn---we will be judged by how we have loved God and others.

I didn't just learn about heresies in the Church---I've been teaching about them for decades now.  You fit the bill perfectly.
