[T]he Father, the Son, and the Holy Ghost [are] three ... not in condition, but in degree; not in substance, but in form; not in power, but in aspect; yet of one substance, and of one condition, and of one power, inasmuch as He is one God, from whom these degrees and forms and aspects are reckoned, under the name of the Father, and of the Son, and of the Holy Ghost.

You can judge the quality of their faith from the way they behave. Discipline is an index to doctrine.

When we are going to enter the water ... in the presence of the congregation and under the hand of the president, we solemnly profess that we disown the devil, his pomp, and his angels.

We first taste a mixture of milk and honey and from that day we refrain from the daily bath for a whole week.

Offerings to propitiate the dead then were regarded as belonging to the class of funeral sacrifices, and these are idolatry. Idolatry, in fact, is a sort of homage to the departed, the one as well as the other is a service to dead men.
