Perhaps; but you are still ignoring scripture that rather explicitly says that your position is incorrect. I suppose your definition of "deliberately" could be different than most.
You may consider the teaching of Jesus on divorce and adultery (Matt 5:32) to be irrelevant to the discussion of divorce and adultery
That is called a strawman argument. I never said it was irrelevant to the discussion of divorce and adultery, I said it was irrelevant to the qualifications of church leadership; the requirements of which are more than (but include) the requirement of marital fidelity.
The standards for Church leaders are indeed more stringent than those for others, and as I said before, it is certainly possible to interpret the Scriptures in restrictive ways. Do you, for example, maintain that a widower who remarries cannot be a church leader?
The marriage vow is generally "till death", so this would be a bit more flexible. But in such a case where the person is devoting his life to the church, he should not re-marry, and such re-marriage is an indication that the candidate may not be suitable.
Do you prohibit someone who smokes (addiction to modern drugs are surely the modern equivalent of the prohibition in 1 Cor 6:10 on 'drunkards').
Yes, smokers, or at least those addicted to smoking (which is probably the majority of smokers) should not have such positions of leadership in the church.
If a father of several faithful children has one child 'go bad' does that disqualify him?
Definitely. The requirement is that his house be in good order, and this would disqualify him just as much as a divorce.
Perhaps it does in your doctrine, and perhaps it should. But I will continue to believe that true repentence, and commitment to Jesus as Lord and Christ, can overcome sin
The issue of church leadership roles is not simply an issue of sin. There is no corruption of blood for sin, as in the case where a father has a disobedient child (i.e., the sins of a disobedient child are not those of the father). Nevertheless, such a situation disqualifies the father from a church position. The requirements for church leadership positions are clearly stated; that they are often ignored by the pseudo-churches in no way changes those requirements.
I would not consider that a cause for disqualification for leadership within the Church for someone who has demonstrated true repentence and honestly desires to serve Jesus
God's word disagrees with you. Just because you refuse to accept God's word in no way changes those words.
My original point was that men who quit on their marriages short of the point of giving up their lives to preserve them have committed a sin. There is no 'no fault' divorce. I offered the sole exception of adultery, strictly because Jesus did.
The exception for adultery was not extended to nor included in the requirements for Church leadership roles. Just because God may allow you to divorce your wife due to her infidelity does not mean that he also grants you an exemption to the requirements listed for church leadership roles. The very fact that a man would marry an unfaithful wife is itself suggestive that he lacks the wisdom to be a proper steward of God's property.
If that's not good enough for you, then I guess you'll have to pick and choose what you will follow.
It is ironic that you would make such a statement, considering that is you who are "picking and choosing" a subset of the bible, using only those scriptures that are to your liking to support your position and ignoring those that directly contradict it.
