I guess context does not matter to you at all.“Then if anyone says to you, ‘Behold, here is the Christ,’(blessed sacrament) or ‘There He is,’ do not believe him. (Matt. 24;23) So much for your blessed sacrament. When you are truly born again your mind will be renewed and you will understand the Scriptures.
The context of that passage concerns the Second Coming of Christ--that is---Christ's coming as judge of the nations.
The Blessed Sacrament is really an extension of the First Coming of Christ; Christ's coming in humility; not his Second Coming--which the passage you quoted is concerned with.
