Simon 'believed?'

Acts 8 tells us that "Even Simon himself believed."It also tells us that "he was baptized."Yet later, Peter spoke to him in a condemning fashion.So, what exactly did Simon "believe?"Will Christians meet him in the new creation?Justin seeks to explain how the issue can be better understood.*Clarification:* it's debatable what it means that the Samaritans received The Holy Spirit. It could have more to do with the manifestation of gifts than being indwelt. Justin says that given his comment that the Samaritans were eventually sealed for the day of redemption.
