n. a demand, a claim, a request or command to come or be present; an instance of asking for something; the act of summoning the Lord, or the Lord’s summoning of his offspring. “And the LORD God called unto Adam and said unto him, Where art thou?” (Gen. 3:9) “Out of Egypt have I called my son!” (Matt. 2:15)
To call: vb. to speak in a loud or distinct voice so as to be heard at a distance; to recall from death or the astral plane, e.g., “Lazarus, come forth!”; to utter in a loud or distinct voice; to announce or read loudly or authoritatively.
The call is the most direct means of communication between man and God, and God and man, frequently used in an emergency; e.g., O God, help me! Archangel Michael, take command!
The byword of the initiate is “The call compels the answer.” “He shall call upon me and I will answer him.” (Ps. 91:15) “They called upon the Lord, and he answered them.” (Ps. 99:6)
