Apostolic Christians were very pragmatic people,accepting that the language of Jesus resonates among Christian in two ways according to their spiritual understanding or lack of it.The Johannine language is actually less symbolic than the other gospels and is more direct to us in regards to the Trinity and can sometimes shock Catholics just as it once shocked the Jews but with familiarity and a little common sense it gives our relationship to Christ and Christianity more depth.

‘For this is why the Word became man, and the Son of God became the Son of man: so that man, by entering into communion with the Word and thus receiving divine sonship, might become a son of God.’[St. Irenaeus, *Adv. haeres]
‘For the Son of God became man so that we might become God.’[St. Athanasius, *De inc.]
‘The only-begotten Son of God, wanting to make us sharers in his divinity, assumed our nature, so that he, made man, might make men gods.’[St. Thomas Aquinas, *Opusc.]" (Catechism of the Catholic Church [CCC] 460)
Yes, Jesus is present in heaven in his full humanity as well as his divinity. The Word became flesh. One of the eternal Persons of the Trinity took on a human nature. And he keeps it, even in heaven.
If I’m not mistaken did not Christ appear to His disciples as man and God. Moving through walls and doors and eating with them and inviting St Thomas to feel his wounds. And what would be the point of perfecting our bodies unless in Heaven we will have both body and Spirit of God, like Jesus.
