I can't swear to it, but I think that Eareckson Tada is a Calvinist.
She shows up at quite a few Calvinist Conventions.
She'll show up at disability Expo's also. She's Evangelical {A non denominational church I think she attends} and has a very good testimony on faith and adversity. When she was 17 she was swimming and did a bad dive breaking her neck and severed her spinal cord at C-4 I think a high quad. That was in 1967. Nearly 40 years in a wheelchair. I've read most of her books and they are very down to earth and inspiring. Much of it follows Paul's teachings on adversity.
She will visit any Christian venue or group. She also has a great singing voice as well. A miracle in itself as singing requires using the stomach muscles which quads generally do not have. She is an accomplished painter. She can not use her hands to do this so she uses her mouth.
She gives the most descriptive insight to the struggle and conflicts a person can have to be struck like this both in the day to day dealing with it and the spiritual struggle as well.
I see no reason why she can't be linked as she runs a NPO. Joni and Friends There is a statement of faith in the site also and a lot of other good information.
When she started her ministry there weren't many churches that even considered the needs of the disabled. Most actually were impossible to even get into with a wheelchair. As more and more persons survive spinal cord injuries and disorders her ministry has reached more and more persons in wheelchairs, their care givers and families, and others who learn of her life.
