Christianity is the only place where a triune (Father, Son, Holy Ghost) God exists. Though "Heavenly Father" is a term that exalts God, we can not exalt Him enough to be worthy of Him. Noting Him as a 'triune God" might even be better as an awareness method to bring the "Father-Son-Holy Ghost" concept to the forefront. That they have gone back to using the term "Father, Son and Holy Spirit" in baptisms suggests that maybe there are people praying that this Synod will move back towards conservative roots. The best way to determine this is by the reaction of its liberal members. If they get cranky then it is most likely true.

That's actually commanded in Matthew 28:19 for baptism, and that's the only time that phrase is used in the Bible. It's not indicative of a "trinity" (a phrase never used in the Bible in any language).
