We ought to be so diligent and firm in standing by the truth, that we not only weigh our own words but also the words of all other persons, in such a manner that no deception, no lie can be concealed therein. A candid mind should never be more displeased with itself than it is, when it finds itself giving utterance to a lie, even under oppression and therefore unwillingly. — Huldrych Zwingli
Interestingly modern politicians and the President Elect have turned deception into something they not only employ but fully admire. This is how we know they are not Christians.
