All of Jesus is holy. It is only by his blood, shed on the cross, that we can become holy.
Holy Mass
You receive the body and blood of Jesus Christ. As Catholics we believe that there is the real presence of Christ in the Eucharist, that it is his body, blood, soul, and divinity.
The Eucharist - the body and blood of Jesus Christ under the forms of bread and wine.
Yes. It is called the Holy Sepulcher.
The Holy Crucifix
The angel Gabriel gave this clear explanation to Jesus' mother, Mary that the holy one will be called Jesus, Son of the Most High. (Luke 1:31,32)
The Christian Holy Book is called the Holy Bible. Christian means a follower of Christ Jesus.
Holy Communion. It is partaking in the body and blood of Christ to confirm your belief in Jesus as your Holy savior.
The Holy Spirit Enters into the Bread and Wine, thus Making it the Literal Body & Blood Of Christ Jesus.
Altar of the spilt blood of the master Jesus
If you mean the Sacrament 'Holy Orders', it was instituted on the night of the Last Supper, Holy Thursday when Jesus called the Apostles to become the first priests by doing as he did - transforming bread into his body and wine into his blood.
The Last Supper is what is celebrated by Holy Communion. When the priest recites the blessing of the Eucharist, he is quoting passages from the Bible when Jesus gave up his body and blood. The wine and bread given to the disciples were symbols of this sacrifice.
