Logical Fallacy of Invalid form using "All"

Invalid form using "all" is a formal fallacy that covers up the problem when reasoning is based on one of the three fallacies of Agrippa's trilemma. Whenever a logical fallacy is committed, the fallacy has its roots in Agrippa's trilemma. All human thought (without Divine revelation) is based on one of three unhappy possibilities. These three possibilities are infinite regress, circular reasoning, or axiomatic thinking. This problem is known as Agrippa's trilemma. Some have claimed that only logic and math can be known without Divine revelation; however, that is not true. There is no reason to trust either logic or math without Divine revelation. Science is also limited to the pragmatic because of the weakness on human reasoning, which is known as Agrippa's trilemma.

"All A are B."

"All C are B."

"Therefore, all C are A."

Examples of the Logical Fallacy of Invalid form using "All"

"All Christians are human beings."
"All people in this church are human beings."
"Therefore, all people in this church are Christians." (invalid form-backwards argument with all)

"All Christians are human beings."
"All human beings are people who have committed sins and need to be forgiven."
"Therefore, all people who have committed sins and need to be forgiven are Christians." (invalid form-backwards argument with all)
