The denial that Christ came in human flesh is called docetism. Hence, the denial that He rose in human flesh is a kind of neodocetism. Both diminish the full humanity of Christ, one before and the other after His resurrection. A similar doctrinal deviation existed in the first century. John addressed it when he warned against those who deny that 'Jesus Christ has come [and remains] in the flesh' (1 John 4:2).

The use of the perfect participle ("has come") implies that Jesus came in the flesh in the past and He remained in the flesh when John penned these words after the Resurrection. In the parallel passage (2 John 7) John used the present tense, warning against those "who do not acknowledge Jesus Christ as coming in the flesh." This makes it even clearer that John considered it wrong to deny flesh of Christ either before or after His resurrection. The reason is obvious: human flesh is part of our true human nature as God created it. Hence, to deny that Christ was resurrected in human flesh is to deprive Him of full humanity.
