Aah… so this isn’t your first rodeo, is it?
How about #356: “[mankind] alone is called to share, by knowledge and love, in God’s own life.” This is a description of heaven!
And while we’re at it, how about #357: “Being in the image of God the human individual possesses the dignity of a person, who is not just something, but someone. He is capable of self-knowledge, of self-possession and of freely giving himself and entering into communion with other persons. And he is called by grace to a covenant with his Creator, to offer him a response of faith and love that no other creature can give in his stead.”
This is critical: only humans are made “in the image of God”, and #357 connects this to the notion of personhood. Among God’s physical creation, only humans can “enter into communion with other persons,” and therefore, only humans are “called by grace … to offer [his Creator] a response of faith and love”. Only humans – “no other creature can give” this response to God!
Also, #1023: “By virtue of our apostolic authority, we define the following: According to the general disposition of God, the souls of all the saints . . . and other faithful who died after receiving Christ’s holy Baptism (provided they were not in need of purification when they died, . . . or, if they then did need or will need some purification, when they have been purified after death, . . .) already before they take up their bodies again and before the general judgment - and this since the Ascension of our Lord and Savior Jesus Christ into heaven - have been, are and will be in heaven, in the heavenly Kingdom and celestial paradise with Christ, joined to the company of the holy angels. Since the Passion and death of our Lord Jesus Christ, these souls have seen and do see the divine essence with an intuitive vision, and even face to face, without the mediation of any creature”.
Notice that what the CCC asserts is that heaven is attained by virtue of baptism. Animals aren’t baptized by the Church, are they?
You realize that when you repeat what I said, it doesn’t actually disprove what I said, right?
