Do you have a passion or a calling God has given to you? I know you do, even if you've not figured it out yet. God's got a purpose for each of our lives. My calling and passion is for the unity of the Body of Christ. I want to keep this post simple:
All of God's churches (little c) are for all of God's people. All of God's people are given as gifts for all of God's people, to be their family and incomplete without each other. All of God's people are all one Church, universal, holy, and eternal.
Dwell on that. Don't let differences in passions or politics (whether they be governmental or adminstrative) divide you. Yes, there are other Christians who don't see themselves unified with you. Choose not to see them the same way. It's a form of love and forgiveness, and a claiming of the truths of scripture.
In Christ's Body, which includes all Christians, there is no 'us' and 'them', there is only 'we' and 'Him', and we and Him are one.
I'm ending there, but if you feel like dwelling on this here are some scripture verses about this topic:
"I, therefore, the prisoner of the Lord, beseech you to walk worthy of the calling with which you were called,endeavoring to keep the unity of the Spirit in the bond of peace. with all lowliness and gentleness, with longsuffering, bearing with one another in love, There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all." Ephesians 4:1-5
"For as we have many members in one body, but all the members do not have the same function, so we, being many, are one body in Christ, and individually members of one another. " Romans 12:4-5
"Now I say this, that each of you says, 'I am of Paul,' or 'I am of Apollos,' or 'I am of Cephas,' or 'I am of Christ.' Is Christ divided? Was Paul crucified for you? Or were you baptized in the name of Paul? " 1 Corithinans 1:12-13
"The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ? For we, though many, are one bread and one body; for we all partake of that one bread. " 1 Corinthians 10: 16-17
"For as the body is one and has many members, but all the members of that one body, being many, are one body, so also is Christ. For by one Spirit we were all baptized into one body—whether Jews or Greeks, whether slaves or free—and have all been made to drink into one Spirit. For in fact the body is not one member but many.
"If the foot should say, “Because I am not a hand, I am not of the body,” is it therefore not of the body? And if the ear should say, “Because I am not an eye, I am not of the body,” is it therefore not of the body? If the whole body were an eye, where would be the hearing? If the whole were hearing, where would be the smelling? But now God has set the members, each one of them, in the body just as He pleased. And if they were all one member, where would the body be?
"But now indeed there are many members, yet one body. And the eye cannot say to the hand, “I have no need of you”; nor again the head to the feet, “I have no need of you.” No, much rather, those members of the body which seem to be weaker are necessary. And those members of the body which we think to be less honorable, on these we bestow greater honor; and our unpresentable parts have greater modesty, but our presentable parts have no need. But God composed the body, having given greater honor to that part which lacks it, that there should be no schism in the body, but that the members should have the same care for one another. And if one member suffers, all the members suffer with it; or if one member is honored, all the members rejoice with it." 1 Corinthians 12:12-26
