Because there are different senses of the word perfect there can be confusion on a statement using it.
The Catechism uses the phrase: “in a state of journeying” towards its ultimate perfection. This shows that complete excellence or flawless is not the initial state. For that reason mankind needed supernatural sanctifying grace and the preternatural gifts, for original justice (of Adam and Eve) yet even then not stable in the will to charity.
