Certainly you have heard Sylvester say it like the clip below.
My mom’s succotash was baby lima beans and corn.

If you look up the meaning most sites say it is a minced oath. A what? Minced oath for suffering savior?
In the mid-1800s, during the Victorian era, there was a rejection of all profanity and so the common people developed a wide variety of malapropisms to avoid swearing on Holy names. Soon, one could hear Cripes and Crikey replace “Christ” and Dangnabit replace “G*d damn it” and Cheese ‘n’ Rice replace “Jesus Christ.” The phrase Suffering Succotash replaced “Suffering Savior.”
Today the latter phrase is known only as an expression of annoyance and surprise by animated cartoon characters such as Sylvester the Cat and Daffy Duck. Was the expression still in vogue when the Looney Tunes cartoons were made, or did the cartoons resurrect an expression that had already lapsed from the American lexicon?

Did they really mean Sylvester was using that in terms of the Suffering Savior I love? I certainly hope NOT!
Suffering well after the manor of those with chronic illness. Me and some friends understand chronic suffering. If you do not have a chronic illness, you probably do not understand what others go through. Yes, you can be empathetic, but understanding usually only comes with the actual experience. I told one friend when she received a chronic diagnosis that we are fortunate if there are 3 or 4 people we can talk to about the details, people we can trust. No cliches, no quick fix Scriptures, no blunt judgement. I cherish those people.
How to embrace the chronic? Some things I have learned include, I am not going to feel better in the morning. Just go with the flow or stagnation. Whichever occurs is current reality. Suffering is said to be when we try to change the current reality, ‘kicking against the goads.’ An ox goad is a wooden tool, approximately eight feet long, fitted with an iron spike or point at one end, which was used to spur oxen as they pulled a plow or cart. Kick against it like an ox and you are likely to get a wound.
About noon, King Agrippa, as I was on the road, I saw a light from heaven, brighter than the sun, blazing around me and my companions. 14 We all fell to the ground, and I heard a voice saying to me in Aramaic, ‘Saul, Saul, why do you persecute me? It is hard for you to kick against the goads.’
Acts 26:13-14 NIV
I understand the need to push back against darkness that wants to distract me from writing about Jesus and talking about Him and living for Him. With a chronic illness diagnosis in 1989 Pentecostals and charismatics said I should resist illness. Yet Jesus told me He would be with me in it. Whom should I believe? I go with Jesus. I pray for healing, but I rest in His Presence and care.
He does not make chronic easy. He does not take it away, but He does make it bearable. He does comfort me. Pain is part of life. Chronic illness can bring pain but some believe that suffering is optional. We avoid suffering by acceptance of what is – in contrast to – wishing things were different.
Jesus suffered. His relationships were disappointing. He suffered unbelief from others. He suffered from being bruised, mocked, beaten, crucified. He died exposed on a cross, feeling separated from the Father. He was buried in a cave. He knows what we feel and what we go through. He walks with us through each occasion. He came to inhabit those very times with us. He knows our misery.
Kicking against reality can create misery. Acceptance does not make the reality go away but it can ease our suffering in the midst. Immanuel, God with us, Eternal gift from the Father. When exasperated by yet another symptom or medication requirement I might say, “Sufferin’Succotash!” I never mean it to degrade what my Savior went through. I just get as exasperated as Sylvester trying to catch the Tweety Bird!
