Its all in the language – Clinton Statesman's Statement

Antinomianism, anti - against, nomos – law , unlawful.
Antinomianism is the polar opposite of legalism, the notion that obedience to a code of religious law is necessary for salvation.

Clinton's denials

Initially, he repeatedly used the present tense "there is not a sexual relationship" with Lewinsky.
what about the past?

The next phase “there had not been an improper relationship”
Some people coin this as - legalistic doublespeak

He didn't "mislead" his family and everone -- he simply lied

Lewinsky informed Tripp that Clinton favored oral sex – that such an act did not constituted adultery. Ms. Lewinsky said in her grand jury testimony that she performed oral sex on Mr. Clinton.

Clinton denied he commited adultery. In his legal defenses, the President tried to distinguish between ''sexual relations'' and oral sex.

The definition of adultery is consensual sexual intercourse with a partner that is not your husband or wife.

Adultery is the voluntary sexual intercourse between a married person and another person who is not his or her spouse. Adultery is also referred to as extramarital sex, philandary or infidelity but does not include fornication. Fornication, or simple fornication, is a term which refers to voluntary sexual intercourse between persons not married to each other. The term "adultery" for many people carries a moral or religious association, while the term "extramarital sex" is morally or judgmentally neutral. (Wikipedia)

In the law of Divorce, adultery is voluntary sexual intercourse with another, one or both of them being married . The intercourse must involve some penetration but need not be complete.

The Old Testament says , that committeth adultery with another man's wife." So adultery meant sexual intercourse between a man and a married woman not his wife. Leviticus 20:10

Go back 2 spaces to why fornication is not adultery.. ?

Nevertheless, Oral sex, for example, would be a violation of your covenant promise ……….. adultery?

In conclusion, remember Clinton’s infamous "I didn't inhale" in respect of when he seen smoking marijuana in his student days at England.

Lets not go that direction.
