The most important distinctive to consider when choosing a church is the teaching and preaching of true biblical doctrine. Human beings made in God’s image are designed to critically discover, know, and believe ultimate truth about God and creation from biblical revelation. We then act on our knowledge and belief in the doctrine taught, preached, and practiced in our church community; we also act in the darkness of fallacy and what is omitted from the teaching. Our spiritual lives then are built or ruined by humbling truths or arrogant falsehoods from the teaching and preaching we continually expose ourselves to, for good or for evil.
An example for warning, beware, in the 5th century in the year of our Lord, Augustine taught Determinism/Compatibilism, a cultic Stoic and Manichean-gnostic doctrine. A thousand years later, this false predestinarianism became the distinctive core element of Calvinism, appropriating the names Reformed, Covenant, and Federal theology in their rhetorical, confessional, systematic, and scholastic traditions. Unfaithful to Scripture, though, and representing the God of Scripture as unjust, unholy, immoral, untrustworthy, and so, unworthy of worship, Calvinism divides the church to this day. This theology is still then rigorously defended in the rhetorical tradition of sectarian apologists, resulting in the spiritual ruin of their hearers. It was in part for this that Jesus warns, “… teaching as doctrines the precepts of men.” Mark 7:6-13, and, “Watch therefore how you listen…” Luke 8:18 God provides His own words in Scripture, as He intended to deliver them. “…the words which I have spoken to you are Spirit and are life.” John 6:63, Hebrews 4:12, 2 Timothy 3:16-17
For the help and protection of you and your family, see the following corrections to the Calvinistic doctrines concerning God, His sovereignty, anthropology, the covenants, salvation, the gospel + predestinarianism, etc:

Divine and Human Freedom, Libertarian, not Deterministic
Both divine and human natures entail libertarian free will, choice, action, and abstinence from action, all essential to personhood and necessary for moral responsibility. Meticulous causal determinism (also called compatibilism) is neither biblical nor correct, contradicts justice and freedom in divine and human natures, and distorts the doctrines of God, man, and their relations. Theological systems then founded upon determinism, for example Augustinian Calvinism, are not correct, harmful, and severe impediments to human spiritual flourishing.
