In Catholic Churches, the Crucifix is accompanied by the Tabernacle, which holds the Body of Christ in the Eucharist, so we know Jesus is present. There is NEVER a time in Mass when we are not reminded that He is Risen, and is with us, ALWAYS.
Yet we were talking about imagery that can be seen with the eye, even to be venerated by some....what imagery can a blind person cling to as a “reminder” of the faith? ( your words)
I’ve cited the example of Fanny Crosby, blind from six weeks, speaking of a different kind of “seeing” when she came to faith...there have been many others.
“The only thing worse than being blind is having sight, but no vision.” Helen Keller, herself a Christian embracing a career of service inspite of her handicaps!
