First off, welcome! My friend and I have wondered for a while how we could best serve the kingdom with our programming skills. We found ourselves doing well in our work, but we felt we could called to do something more impactful than that. Then came the realization that we could improve upon existing free software, as well as provide brand-new free software, specifically for the church and the spread of the Gospel of Jesus Christ.
For the immediate time being, if you can agree to the Apostle's Creed and you maintain the Bible as the inspired, infallible Word of God, we won't struggle to call you a brother or sister in Christ. If we feel the need to clarify on any more theological points or stances, we will add these as necessary.
I believe in God, the Father almighty, maker of heaven and earth; And in Jesus Christ, his only Son, our Lord; who was conceived by the Holy Ghost, born of the Virgin Mary, suffered under Pontius Pilate, was crucified, dead, and buried. He descended into hell. The third day he rose again from the dead. He ascended into heaven, and sitteth on the right hand of God the Father almighty. From thence he shall come to judge the quick and the dead. I believe in the Holy Ghost, the holy catholic Church*, the communion of saints, the forgiveness of sins, the resurrection of the body, and the life everlasting. Amen.
