Steps are a huge problems when you have people in wheelchairs or people who are feeble.
That was one of the reasons we sold our lovely old building and built a new one. Our elders are much more comfortable in the new and as a result they are able to attend every service rather then just when they are feeling at the top of their game.
I do miss our stain glass windows though.
My old church (which is over 125 years old) put in a concrete ramp back in the 70s. Most of the older churches that I’ve been to have been retrofitted with ramps and have been making accomodations for the elderly. They try to remove all the obstacles to worship that they can.
