The sacramental presence of Jesus in the Eucharist is not more real than the indwelling of the Holy Spirit within the Christian. The distinctions between the two are not based in levels of reality.
Please keep in mind that the Eucharist is the body, blood, soul, and divinity of Jesus. Jesus had a human body and soul*. Likewise, Jesus had His divine nature. The hypostatic union of the two are what make up the person of Jesus.
The indwelling of the Holy Spirit is just as real but it is a spiritual indwelling that does not include the body, blood, and soul of Jesus. The absence of Jesus body and blood does not make the indwelling of the Holy Spirit less real.*
Thank you for your clear explanation. So there is no difference in the “realness”, only in the characteristics. Is that correct?
