Oh, pleeeze!  During the 1 and 2nd Centuries of Christianity there were NO CHURCHES at all.  People attended home churches and celebrated THE MEAL [as the Eucharist] was called then on the Day of the Lord---Sunday.
There was no crucifix, no tabernacle, no kneelers, no altar rails any where in these homes.  The Christian communities grew and grew.  This was not because of any of these items.  The Church grew because the PEOPLE of these Christian Communities demonstrated the Life of Christ present in them.  What drew others to become Christians themselves was what they observed "See how they love one another" and not 'look at the crucifix, tabernacle, statues and kneelers in the church.'

Unless Christian/Catholics themselves demonstrate vividly the life of Christ living in them, nobody is going to go from the streets into any church to look at crucifixes, tabernacles, altar rails, statues and kneelers.
