First of all, our stance against serving on a jury is based on many Biblical passages, not just on the requirement of two eye witnesses. Even if two honest eye witnesses were available to testify against an accused, a true Christian should still not participate in the jury system of this world. For a further in-depth discussion of this vital question, please read our Q&A’s in Updates #289 and #66.
In Update #66, we state, indeed, the following, after having discussed numerous additional principles prohibiting true Christians to serve on a jury:
“In following the biblical injunctions, one could not convict a person, in any event, unless the accusation is supported by the testimony of at least two witnesses (John 8:16; Deuteronomy 17:6-7). Since the witnesses would have to ‘cast the first stones,’ circumstantial evidence would not be sufficient, under God’s law, for the requirement of two witnesses.
“Since we may be required, as a juror, to apply man’s laws in conflict with the law of God, we could not take the oath as a juror, as we would, in principle, agree to obeying man rather than God (Acts 5:29; Acts 4:19).”
