G.W.
Christian preschools do not teach theology nor doctrine. They simply teach that God created the world, He loves each of us and takes care of us, is a comfort in times of need and sent his Son to live on the earth for awhile to teach us more about himself and how to be more like him. Now, there very likely will be a time where Jesus's death on the cross is taught in a very gentle way but obviously that is the basis of the existence of the Christian faith so if one doesn't believe or agree, then that type of preschool is not appropriate for his/her children....a secular option is better. While there are some fundamental doctrinal differences between Catholicism and Christianity, I believe the core foundations I mentioned above are the same so I wouldn't think there would be too big of a problem for you. Obviously, taking your child to your home church for regular worship plus what you teach at home will make up what you feel is missing. I think you'll be fine :-)
