Yes, as there are clergy who are gifted to teach, as well as laity to do such in say Sunday School/cell groups.Actually, the "pastor/teacher" paradigm from Eph. 4:11 is based on a mistaken usage of the Granville Sharp rule, which applies to singular nouns in that usage but not plural ones as in that verse. So a teacher is not necessarily a pastor and vice versa. One can be both or either.
