Luther ended a long Good Friday meditation, actually a tract with these words –

And they are called true Christians who incorporate the life and name of Christ into their own life, as St. Paul says in Galatians 5: 24: “And they that are of Christ Jesus have crucified the flesh with the passions and the lusts thereof.” For Christ’s Passion must be dealt with not in words and a show, but in our lives and in truth. Thus St. Paul admonishes us in Hebrews 12: 3: “For consider him that hath endured such gainsaying of sinners against himself, that ye wax not weary, fainting in your souls;” and St. Peter in his 1 Epistle 4:1: “As Christ suffered in the flesh, arm ye yourselves also with the same mind.” But this kind of meditation is now out of use and very rare, although the Epistles of St. Paul and St. Peter are full of it. We have changed the essence into a mere show, and painted the meditation of Christ’s sufferings only in letters and on walls.
