Not quite. Lots of theologians debate what Christ revealed in the transfiguration, among them, that Christ is the culmination of the Law (as represented by the presence of Moses) and the Prophets (as represented by Elijah). Christ was between them and they directed their conversation to Him. God the Father said "Listen to Him", referencing His Son. God mentioned neither Moses nor Elijah when He spoke. Take the hint from God Himself: listen to Christ.
I do listen to Christ.
lol!!!
