The answer
St. Cyril of Jerusalem says, “Again, He is called a Lion … indicating as it were by the title His kingly, and steadfast, and confident nature: a Lion He is also called in opposition to the lion our adversary, who roars and devours those who have been deceived … [He is] the strong Lion of the tribe of Judah.”787
