Jesus was baptized in the Jordan River. He touched the waters and thereby sanctified them for our baptism.
Jesus fasted for 40 days in the desert before beginning His public ministry. He "touched" fasting thereby sanctifying it as a practice we should all embrace.
Jesus "touched" suffering. He suffered immensely and He suffered well. His touch sanctified suffering and made it something that we should long to do well.
St. Paul wrote in his letter to the Colossians (Col 1:24) "Now I rejoice in my sufferings for your sake, and in my flesh I am filling up what is lacking in the afflictions of Christ on behalf of his body, which is the church."
Fr. John Riccardo explains that what is "lacking in the afflictions of Christ" is our participation in them.
People in my age group and older were taught to offer it up when we had a headache or other type of pain we were dealing with.
I have learned over the years, from great teachers, that in addition to offering up our suffering, we should also UNITE our suffering with that of Christ's.
We will all suffer. It is an inevitable fact of life as a consequence of original sin. For many, it is definitely their path to sanctification. It doesn't matter how little or big the suffering is. From an annoying headache, a broken bone, loneliness, or cancer, uniting it to Christ's suffering sanctifies not only us but the suffering as well.
