It is the struggle of the finite mind determined to impose limitations on the infinite in order to facilitate credibility. So mystery A is possible, mystery B is not. It is human mentality at once arrogant, yet inferior. If the eucharistic presence were referred to with some regularity from the pulpit, faith would be strengthened. When something is ignored the result is unfamiliarity, which breeds indifference.
Some priests know the remedy.
One such is my pastor, who initiated perpetual adoration in our church. To the astonishment of skeptics, it grew from a few modest hours to twenty-four hour observance. Whereas other churches are dark and locked aside from Mass, ours is always lit and open. Parishioner sign-ups cover every hour. It is inspirational to visit and find people silent in individual prayer, or in communal recitation.
