one core tenant of Christianity is that Christ the Messiah obviates prophecy. No denomination of Christianity (AFAIK) considers the LDS as true Christians...except for the LDS themselves
Just to clear this up, all the various "Christian" ministries that embrace modern prophecy and prophets are, therefore, not actually Christian?
From the beginning of the Assemblies of God, prophecy has been affirmed as a spiritual gift for the Church today. Since the Day of Pentecost, the Church has functioned as a prophetic community. Any Spirit-filled believer may prophesy while discernment and judgment of prophecy belong to the full body of Christ.
And to make it clear since you didn't say it, Assemblies of God is on the list categorized as Christian while the LDS Church isn't, so this doesn't appear to be the distinction the list makers had in mind.
