Oops. You say "Lutheran Churches." There is more than one of them.
Most Lutheran churches are ELCA, Evangelical Lutheran Church in America, but there are others, perhaps the most noted being the Missouri Synod Lutheran Church.
ELCA has just signed an agreement that makes it essentially united with the Episcopal Church. As you would expect, this branch is a reasonably liberal denomination (not much literalism, although you will find it in all denominations to some extent). It is liturgical -- that is, it has a written-down ritual for how exactly to conduct the different services.
Missouri Synod folks tend to be much more conservative and there you will find a lot more literalism in interpreting the Bible.
This makes the Missouri folks much closer to the Pentecostals (capitalize, please).
The Pentecostal denominations (there are many variations) tend to emphasize the gifts received by the Church on Pentecost, which would be glossolalia (speaking in tongues), direct revelation to the faithful, being slain in the spirit and other experiences that give the worshipers a very clear, personal demonstration that God is with them in their worship.
I do not think that Pentecostal denominations have any written liturgy at all. They would frown on such things: they prefer to leave themselves entirely open to direction inspiration by the Holy Spirit.
