The presbyterate and the necessary apoptosis

In biology, there is a process which we, as the Church and above all as priests, would do well to observe carefully: a healthy body knows how to let die what is killing it. It is called cellular apoptosis, and it is one of the most extraordinary mechanisms in our organism. It is defined as “programmed cell death”: when a cell is damaged, corrupted or ceases to work for the good of the whole, the body itself recognises it and eliminates it. It does not hide it, it does not transfer it to another tissue, it does not cover it up hoping it will heal on its own. It expels it. It is the body saying to that cell: “You must go, because you are becoming a danger to me”. When this mechanism breaks down, and damaged cells remain where they are and begin to multiply, a tumour develops. A healthy organism does not protect what makes it ill: it lets it go. This is how, and only how, the life of the whole is preserved.
