"Do you have faith in and a testimony of God the Eternal Father; His Son, Jesus Christ; and the Holy Ghost?”
Lectures on Faith tells us that God "is the object in whom the faith of all other rational and accountable beings centers, for life and salvation." Since the scriptures regularly talk about having faith in Christ specifically (see, for instance, Moroni 7), it makes sense to have faith in Christ as well. But can you find anywhere in scripture that talks about having faith in the Holy Ghost? D&C 20, as well as Mormon 7, talk about the Father, the Son, and the Holy Ghost as "one God", so perhaps that makes faith in the Holy Ghost a meaningful idea. But if, as Lectures on Faith attests (lec. 3, para. 4), to have faith in God requires "a correct idea of his character, perfections, and attributes" (emphasis in the original) wouldn't we require the same sort of knowledge in order to have faith in the Holy Ghost? Does the Church generally proclaim that it has any such idea? My memory of Sunday School includes no such detail. We know of his mission, but not much else. Can we reasonably have faith in the Holy Ghost?
