Now, taking this definition, along with the acts and words of Jesus as found in the three narratives already quoted, we find that there are five elements in every ordinance. These five must be in every Christian ordinance, or in every ceremony claimed to be an ordinance. Divine authority, specifically named in the definition, and conceded by all Protestant authorities and creeds. The second element is formal observance. There must be an outward, visible sign, or form, in an ordinance.
Prayer is an ordinance of divine worship.
But it is not a rite, or ceremony. Men are commanded to pray always. Charity is an ordinance, but it is devoid of ceremony. We ceremonially observe baptism, the Communion, the washing of feet. This is what Christ did.
