150 THE TREATISES OF CYPRIAN. " He who saithhe abidethin Christ,ought himselfalsoto walk even as He walked."1 Also in the same place: "Love not the world,neitherthe thingsthatare in the world. If any man loveththe world,the loveof the Father isnotin him. Because everythingwhich isin the world islustofthe flesh,and lustof the eyes,and the ambitionof thisworld, which is not of the Father, but of the lustof thisworld. And the world shallpass away with itslust. But he that doeth the willof God abidethforever,even as God abideth for ever."s Also in the firstEpistleof Paul to the Corin thians: " Purge out the old leaven,that ye may be a new dough, as ye are unleavened. For alsoChrist our passover i3sacrificed.Thereforeletus celebratethe feast,notinthe old leaven,nor in the leavenof maliceand wickedness,but in the unleavenedbread of sincerityand truth."3 12. That we must not swear. In Solomon : " A man thatswearethmuch shallbe filled with iniquity,and the plagueshallnot departfrom hishouse; and if he swear vainly,he shallnot be justified."4 Of this same matter,accordingto Matthew : " [Again,ye have heard thatitwas saidto them of old,Thou shaltnot swear falsely, but shaltperform unto the Lord thineoaths.]I sayuntoyou, Swear not at all: [neitherby heaven, because itisGod's throne; nor by the earth,becauseitis His footstool; norby Jerusalem,becauseitisthe cityof the greatKing; neither shaltthou swear by thy head,because thou canst notmake one hair white or black.] But letyour discoursebe,Yea, yea ;Nay, nay : [forwhateverisfullerthan theseisof evil."]5 Of thissame thing in Exodus : " Thou shaltnot takethe name of the Lord thy God in vain."0 1 1 Johnii.6. 2 1 Johnii.15-17. s 1 Cor.v.7,8. 4Ecclus.xxiii.11.
