Yesterday i caught the homily reading on a private channel televising like every saturday pm the Mass in Prato Cathedral, explaining the institution of the Corpus Domini, the Eucharist. When the presiders and the others were serving the Eucharist to the people streaming to the altar there was Jesus. In the hands of the ministers and in the hands of the ministers, the offering hand and the Body being offered. Like he gave himself to those historically alive spraeding the teachings of the Father and embodying them from conception in the womb of the Virgin Mary till the excruciating death on the cross. He also told about the miracle of Bolsena (the corporal being in Orvieto Cathedral built to enshrine it). NB The miracle is still not officially recognised but the Church and treasured as private revelation.

You shall not provoke thy Lord. Jesus does not need to prove himself if provoked. healing those who need is another matter. Asking for proofs is an indication of pride.
