This clause is exceedingly obscure. Harvey remarks upon it as follows: “The reasoning of Irenæus seems to be this: According to the Gnostic theory, the Æons and angels of the Pleroma were homogeneous. They were also the archetypes of things created. But things created are heterogeneous: therefore either these Æons are heterogeneous, which is contrary to theory; or things created are homogeneous, which is contrary to fact.”
