People often refer to 1 Corinthians 3:16 as the reference to our body being God’s temple. However, the word “you” is plural and is referring to the church at Corinth along with the Church as the body of Christ (see the footnote in the reference link above). The concept is still valid though with 1 Corinthians 6:19 being the reference.

1 Corinthians 6:19-20
Or do you not know that your body is a temple of the Holy Spirit within you, which you have from God, and that you are not your own? ²⁰ For you were bought with a price; therefore glorify God in your body.
