Weighing liberalism and Christianity in the balance is a delicate matter.
Jesus Christ wasn't an attorney at law, and Paul was. Paul had been a member of the Jewish Sanhedrin Council, which is the "Israeli Supreme Court", in the same way that the Council of Elders (Dreidel Council) is the aristocracy of Monarchial Israel, or at other times in Israel's history when Israel is without a genealogical King, similar to the Senate, but strictly hereditary. The Israelite government is more interesting than you think it is, you should really check into becoming a liberal sometime.
If you're really a Christian in Holy Orders, as defined by United States Constitutional codes, including military law, one thing you have to be willing to do is practice Christian faith in the manner of Christ, meaning that you are in a religious order. The professions of clergy members are not strictly limited to theology graduates with congregations, this seldom comes up except in the draft, but a medical doctor or a teacher of most anything (engineering, say, or even fine art) might sue the draft board to be released from combat duty because he already has an expensive education in a realm that is complete and useful to the state, which in and of itself doesn't require him to be an athletic fencer or shooter. Farmers can be exempted from the draft, it's nothing to do with accountants and bankers or property law, it's something to do with the fact that the country including the Army needs what farms produce to survive.
If you accept noncombatant status, you still have to be willing to die for your faith. Jesus was murdered by the usurper King Herod Agrippa, he had been baptized and was the Messiah, commonly called a rabbi and considered a Jewish teacher. Well, actually, it's less that He was a teacher than that He was a priest. That He was a priest is legally and religiously viewed as being demonstrated by the fact that He performed miracles.
You can be a Christian all day every day for the rest of your life and just put up with the government, see if I care.
There's also the profession of the law.
