Why is it Christians cannot agree to the point where they have condemned each other to hell and/or slaughtered each other because of doctrinal differences that other Christians don't think are essential for salvation? My answer is that Christianity is man made, and as such, doctrinal differences are due to different human ways of understanding the Bible. There is no divine mind behind the Bible, otherwise God should have communicated his will much better than he supposedly did. That's the major reason why there is no doctrinal Christian unity. These different doctrinal understandings continue to be used by denominational leaders to differentiate between Christianities for financial gain and power. Christian, what's your answer?
A truly facepalm inducing paragraph causing groans to match. I'm amazed at this. Apparently to John Loftus, anyone who claims to be a "Christian" is just as "Christian" as anyone else, no matter what they believes. In order to even begin such a silly argument, this presupposition must be in it's centerpiece. Along with the the thought that all denominations of Christianity are so different that we can't even begin to live peaceably. Another false canard. I'm not saying that there haven't been wars fought and mistakes made - but these were human mistakes not God's. Also I am not saying that there aren't important differences, but none are important enough to kill another over. The reason why we have so many problems because we have refused to obey the word of God. On nonessential issues this what the Bible says:
1 Accept the one whose faith is weak, without quarreling over disputable matters. 2 One person’s faith allows them to eat anything, but another, whose faith is weak, eats only vegetables. 3 The one who eats everything must not treat with contempt the one who does not, and the one who does not eat everything must not judge the one who does, for God has accepted them. 4 Who are you to judge someone else’s servant? To their own master, servants stand or fall. And they will stand, for the Lord is able to make them stand.
5 One person considers one day more sacred than another; another considers every day alike. Each of them should be fully convinced in their own mind. 6 Whoever regards one day as special does so to the Lord. Whoever eats meat does so to the Lord, for they give thanks to God; and whoever abstains does so to the Lord and gives thanks to God. 7 For none of us lives for ourselves alone, and none of us dies for ourselves alone. 8 If we live, we live for the Lord; and if we die, we die for the Lord. So, whether we live or die, we belong to the Lord. 9 For this very reason, Christ died and returned to life so that he might be the Lord of both the dead and the living.
10 You, then, why do you judge your brother or sister? Or why do you treat them with contempt? For we will all stand before God’s judgment seat. 11 It is written:
“‘As surely as I live,’ says the Lord,
‘every knee will bow before me;
every tongue will acknowledge God.’”
12 So then, each of us will give an account of ourselves to God.
13 Therefore let us stop passing judgment on one another. Instead, make up your mind not to put any stumbling block or obstacle in the way of a brother or sister. 14 I am convinced, being fully persuaded in the Lord Jesus, that nothing is unclean in itself. But if anyone regards something as unclean, then for that person it is unclean. 15 If your brother or sister is distressed because of what you eat, you are no longer acting in love. Do not by your eating destroy someone for whom Christ died. 16 Therefore do not let what you know is good be spoken of as evil. 17 For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, 18 because anyone who serves Christ in this way is pleasing to God and receives human approval.
19 Let us therefore make every effort to do what leads to peace and to mutual edification. 20 Do not destroy the work of God for the sake of food. All food is clean, but it is wrong for a person to eat anything that causes someone else to stumble. 21 It is better not to eat meat or drink wine or to do anything else that will cause your brother or sister to fall.
22 So whatever you believe about these things keep between yourself and God. Blessed is the one who does not condemn himself by what he approves. 23 But whoever has doubts is condemned if they eat, because their eating is not from faith; and everything that does not come from faith is sin. - Romans 14
