I`m not sure if this post was intended to sound as a joke but in case it wasnt - please note that we shouldn't say Kiril and Methodius - we should always say St. st. Kiril and Methodius. They are saints for both catholic and orthodox churches and are of great importance for all Slavonic countries. As for the name of the alphabet - this is a later edit, the 2 brother actually created an alphabet called Glagolitsa (Glagolitic) - it had 44 letters out of which 24 looked like Greek. 
PS: we have a special category for  letters like ш, ж, щ, ц and ч. Bravo for the instincts!
