Anony Mous : the idea that somehow it’s okay to pay your taxes but not aid in the military is backwards.
AM, I accept most of what you say, although it is new to me that a criminal record due to "neutrality" would bar one from having certain responsibilities. That's anal. But on the matter of taxes, some conscientious objectors (not JWs) have refused to pay the proportion of their taxes they believed went towards the military. I considered that but concluded that Jesus' statement on tax (Matthew 22:17-21) settled any reservations about what the tax might be spent on.
NotFormer : In most countries, civilian service in lieu [of military service] can be things like building roads, etc.
Jesus was not talking about doing something in lieu of military service. I gave the example of Simon of Cyrene who was compelled (ἠγγάρευσαν) to carry Jesus' stauron, the same word (ἀγγαρεύσει) Jesus used at Matthew 5:41. This was not in lieu of an alternative. If you do some work in lieu of military service, you are recognising your obligation to perform military service and substituting some other work. As Anony Mous points out, this is the viewpoint the Watchtower held and nothing was acceptable in lieu of military service, including paying a fine. In 1996 it was made clear that it is a matter of conscience whether or not one accepts work instead of military service. The conscience of the great majority has since allowed them to perform alternative service, but that is human nature for you. The principles have not changed, but with the variety of governmental responses to conscientious objectors and the fact that many young men didn't understand the nuances of refusing alternative service, the issue is more that of conscience than a clear scriptural mandate.
