On the other hand, essential properties are those that are part of the essence of a thing. Remove that property, and it ceases to be that thing. Sin is not essential to humanity, unless someone believes that God made humanity sinful at the beginning. If sin is essential to humanity, then that would mean Jesus was either sinful or not human. So, sin is not essential. Adam had no sin when he was created, yet he was still human. Jesus has no sin, but He is still human. Believers will have no sin when they get to heaven, and they will still be human.
