Well, if you want the JW answer, according to the 1952 Watchtower:

This setting shows that Jesus was not talking about his physical body, but “he was talking about the temple of his body”. The temple in Jerusalem that Jesus cleansed represented not Jesus alone but also the body-members over which he is head. Just as the literal temple was not made up of one stone but many, so “the temple of his body” consists of many living stones, with Jesus as the foundation cornerstone: “You yourselves also as living stones are being built up a spiritual house for the purpose of a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ.” (1 Pet. 2:4-7, NW) After the Jewish religionists rejected Christ the living stone and broke him down by death on the torture stake, on the third day thereafter Jehovah God raised him up to become the chief cornerstone of the temple of living stones then under preparation. He immediately appeared to his disciples and lifted them up out of their despondency, built them up spiritually so that they could “offer up spiritual sacrifices acceptable to God”. That this building of “the temple of his body” started then and continued through the years that followed is shown by Peter’s use of the present tense when years afterward he said Christ’s followers “are being built up a spiritual house”.
