The sixth transfiguration of the Lord was that of the resurrection, when he was transfigured from passion to impassibility, from death to immortality, and put on beauty and strength.

This was a vestige of what occurred on the mountain; that transfiguration was a foreshadowing of this one, as was noted above.

The seventh transfiguration was that of the appearance in which he showed himself to his disciples after his resurrection.

This appearance is called a transfiguration because he did not then show them the form of immortality, majesty, and glory which he then in fact had, but rather he appeared in the state, form, and shape he had when he was still mortal.

He did this so that they would recognize him, and believe that he had truly risen. If he had appeared in that glorious form they would not have recognized him, but would have thought he was someone else.

The eighth transfiguration is that of the ascension. Although it is not set down explicitly in writing, we should believe that in the ascension when, as the apostles were watching, ‘he was raised into heaven and a cloud received him’ (Acts 1:9-10), he revealed the form of his glory and majesty so that by doing so he could rouse the hearts of the disciples to follow him.

Hence it is also written: ‘As you have seen him going, so will he come’ (Acts 1:11).

Since he is to come in the form of majesty (Mt 25:31), we can conclude that he was seen to ascend in it as well.

His ninth transfiguration occurred on Pentecost day, in the spirit and hearts of his disciples, when the Holy Spirit descended upon them in tongues of fire and filled them with charity and love.

When they had received these endowments they no longer thought of Christ in the usual, fleshly way, but spiritually, even when they thought of his body.

They no longer thought about him as someone who worked miracles on earth in a mortal way, but as one seated in heaven at the right hand of Majesty.

We should describe this as a transfiguration of the apostles rather than of the Lord.
