I don't believe that. Peter says that we have been called for this purpose because Christ suffered for us as an example that we should follow in his steps. I pray that I might be considered worthy to suffer for his sake.
Jesus says:
Matt 11
28 “Come to me, all you who are weary and burdened, and I will give you rest. 29 Take my yoke upon you and learn from me, for I am gentle and humble in heart, and you will find rest for your souls. 30 For my yoke is easy and my burden is light.”
Every human suffers, I am watching those in Ukraine and those in the floods, saved or unsaved. Yet Jesus says we take up HIS yoke and LEARN from HIM (not the RCC) that it is light. With Jesus no matter what we suffer, He is with us and we have the comforter.
What are your praying for stigmata? I would pray no matter what we go through we stay the course. I know that Christians in the suffering countries, see the Western Christians as weak. I have prayed no matter what, no matter the threats that I never waver and that God strengthens me.
But really more importantly I want to love as Jesus loves even my enemies. It is more important than suffering. I want to act as He would act in situations. I want my mind to be like Christ. To keep your eyes on Jesus, no matter what. To get the first right is the most important.
I see you avoided answering what was Paul's affliction, what was his suffering. You avoid answering very relevant questions from all posters.
Real suffering for an RC would be to understand scriptural repentance and do it. That would alter their lives forever.
