The Teaching of Tradition that support the Council of Trent interpretation on death penalty cited the reflections or teaching of St. Thomas Aquinas and St. Augustine:
"They will never be beasts, but they can behave like beasts. "And if they behave like beasts, their dignity will suffer loss", while their personhood remains. Therefore we destroy the body, and leave the soul in God's hands, it is an appeal to the Highest Court. There is a difference between the dignity we have being made in God's image and the dignity of our bodies which are NOT made in God's image, and aka Catholic underlines it." – (St. Thomas Aquinas himself and St. Augustine himself quoted from comment of other user)
From above teachings, I found a lot of reflections not yet certain or are open for better understanding like:
They will never be beasts, but they can behave like beasts. (Is an admission of conditional behavior).
"And if they behave like beasts, their dignity will suffer loss,” while their personhood remains. (The words "will suffer loss" again is not certain and will have difficulty to guarantee that a soul really has lost its dignity in the absence of human faculties as we are commanded not to judge in Matthew7:1).
Therefore we destroy the body, and leave the soul in God's hands, it is an appeal to the Highest Court. (The wordings can be clearly seen "as an appeal a prayer only subject to the Wisdom & Providence of God", so they are recognizing that Tradition does not have a Final Say on ending one's life).
But, the most troubling one is the teaching separating the dignity of man soul to the dignity of the his body.
“There is a difference between the dignity we have being made in God's image and the dignity of our bodies which are not made in God's image,"
This particular phrase on Tradition seems emphasizing the physical body is not made in God's image only the soul.
My understanding is the soul animates our body and while it is our soul that will be judge in the end by God,the Church teaches the resurrection of our bodies.So, our judged soul will be reunited to our resurrected bodies.
My question, what is the scriptural basis of the teaching that the dignity of the soul is separate from his body?
I'm looking for Catholic Church Teaching that will expound and put clarity on the issue of the inherent dignity of man (body & soul), which the Council of Trent said "will suffer loss" that is put now to better understanding under Pope Francis "that man's dignity is not lost even after committing a very serious crimes."
