Jefferson certainly believed in the supernatural. He believed in God. He believed in angels, and Satan, he believed in Prayer and believed that God did intervene in the lives of men. (I have dozens of letters, quotes, from jefferson supporting this)
Jefferson despised the corruption of Christ's words by men who tried to seek advantage over other men. He despised the corruptions of the Catholic church. he did not agree that Christ was God, nor do I. Christ was the Son of God, not God Himself.
Funny, Mylo, but you choose to ignore the many more quotes of Jefferson when he claims to be Christian.
In Protestantism no man tells another man whether they are Christian or not. Each man himself claims their discipleship to Christ.
You can also be Christian without belonging to any specific church (though Jefferson attended several on a regular basis depending whether he was in Virginia or Washington)
Jefferson prayed to God, followed the teachings of Christ and shared the Gospel with others (he wrote books about Christ). I have hundreds of quotes of his supplications to God.
By definition Deists do not pray to God, nor do they believe in an afterlife. Jefferson did both.
You cannot deny Jeffersons own profession of faith in Christ.
You cannot ignore Jeffersons belief in an afterlife and judgment by God.
