What took place in the temple which couldn't take place in the synagogue and never takes place in our churches today?

In the temple, the primary ritual of animal sacrifice took place, which served as a means of atonement and worship, a practice not conducted in synagogues. The temple was also the location of the Holy of Holies, where the presence of God was believed to dwell, and only the High Priest could enter it once a year on Yom Kippur. This level of sacredness and ritual intimacy with God is not replicated in modern churches today, where such practices and the concept of a singular, divinely ordained space have evolved.
