This seems to be an American thing. It is...odd to me that a pastor would call you up on the carpet for not agreeing entirely with the church constitution and demand you accept it wholesale. So long as you don't go about the church sowing antagonism toward the constitution, it should be no problem for you to remain in membership in the church. No two thinking people agree entirely on everything.
Well, the common denominator is you, then, isn't it, not the churches you've tried to join.
Again, this is very odd. How do they all know what your convictions are? Do you have to publicly announce them to the congregation? Can you not keep your point(s) of disagreement with the church's Statement of Beliefs to yourself?
This seems to me to be something you could have very easily kept to yourself. Certainly, this is not an issue over which you should be constantly dividing from the Body of Believers. I am a teetotaler; never had a drink of alcohol in my life; never will. But my wife has the occasional glass of wine, or, now and then, a cup of honey mead. She knows I don't like it that she drinks alcohol but I know that the Bible doesn't outright forbid consumption of alcohol. So, we give each other room to be persuaded by God on this matter in His time. It is absolutely not a matter over which to argue and divide - unless the consumption of alcohol has led to drunkenness.
Personally, I can find little reason in Scripture for drinking alcohol but a great deal of reason in Scripture for not doing so. While drinking alcohol may not be sin, it is, I am convinced, what Hebrews 12:1 describes as a "weight," adding the totally unnecessary risk of sin (drunkenness) to the believer's "running of the race," and creating a potential for offense and stumbling among fellow believers that a mere preference for alcohol just doesn't justify.
In any case, the occasional, well-controlled consumption of alcohol is not grounds for the dis-fellowshipping of any believer. That goes in both directions, though. The church shouldn't be ejecting you from its ranks for drinking the odd glass of wine or bottle of beer, and you should not be so dedicated to this totally unnecessary practice that you are forsaking the Body in order to maintain it.
Love, brother, is the guiding principle here - a love that is self-sacrificing, that seeks the welfare of the other before one's own (1 John 4:7-11). This is Christ's example to us. Are you willing to sacrifice your drinking for the sake of your spiritual family, many members of whom have a great sensitivity to the consumption of alcohol? If not, I would suggest to you that it isn't godly love that is motivating your unwillingness. In love, Christ shed his blood and gave his life for your sake. But you can't bring yourself to yield up the luxury of alcohol for the sake of your brothers and sisters in Christ? Something's wrong, brother, with your priorities, with your understanding of what it means to love the family of God as He has called you to.
Romans 14:15-21
15 For if because of food your brother is hurt, you are no longer walking according to love. Do not destroy with your food him for whom Christ died.
16 Therefore do not let what is for you a good thing be spoken of as evil;
17 for the kingdom of God is not eating and drinking, but righteousness and peace and joy in the Holy Spirit.
18 For he who in this way serves Christ is acceptable to God and approved by men.
19 So then we pursue the things which make for peace and the building up of one another.
20 Do not tear down the work of God for the sake of food. All things indeed are clean, but they are evil for the man who eats and gives offense.
21 It is good not to eat meat or to drink wine, or to do anything by which your brother stumbles.
1 Corinthians 8:12-13
12 And so, by sinning against the brethren and wounding their conscience when it is weak, you sin against Christ.
13 Therefore, if food causes my brother to stumble, I will never eat meat again, so that I will not cause my brother to stumble.
1 Corinthians 10:31-32
31 Whether, then, you eat or drink or whatever you do, do all to the glory of God.
32 Give no offense either to Jews or to Greeks or to the church of God;
