From a Methodist Church (Mission) Chair?

This 'Mission' - (Stickley) styled chair has sister rocking chair. Bought as a pair in 1986 in Brimfield for around $350. As shown the backs have cut-outs and the arm fronts appear to be crosses...or just the construction? The pair was noted to of been purchased from a Methodist Church? Any thoughts of origin/maker would be great! Thanks in advance!
