In the context of what you said, for people who are “perfectly well” (which is almost no one, so it is meaningless without qualifications) it would violate Jesus’s words to get one of the COVID vaccines. That is as erroneous an interpretation as it is dangerous. You are implying that people who are “perfectly well” would violate Jesus’s words if they went to a doctor.
No, I was attempting to get to answer by first asking you some questions in reply, which you didn’t answer. But I have already given the answer to which I was heading: your interpretation is deeply flawed because you are divorcing it from the context and using it as a pretext to support your position on the COVID vaccines. Very erroneous; very dangerous.
