I suppose someone might be attracted to the Church by the beauty of the churches and robes but I don’t think it’s that many.
I wrote in an earlier post that the iconography, etc. “feeds” the faithful. The church I go to has a booklet that gives a “tour” of the church descibing the symbolism of the stained glass, the statues (why those saints are featured), the 12 steps leading up to the church, even symbolism of the acanthus embellishment at the top of the pillars. That church is a catechism and one can’t look anywhere without being reminded of God.
And unfortunatly most newer churches are simple, to the point that they don’t even seem Catholic. The parish church I was baptised in was renovated a couple of decades ago and was stripped of nearly every thing that made it seem Catholic. The statues that remained were whitewashed (they have been restored, thankfully), there wasn’t a crucifix in the sactuary for years (the original was placed in the school) and the stained glass symbolizes the environment (earth, sky, water) with a nod the the seven sacraments represented by seven half-dollar discs of glass. There was very little that might offend a anti-Catholic protesant, pagan or atheist. No mystery, no beauty, no wonder.
I’ve also noticed that older churches often feature architeture common in the country that the saint was from. So if the church was St. Bernadette’s it had a notable French style to arches, windows and doors. they could be so simple but they made it feel like you could be in a church that the saint prayed in.
