While the Acronym is generally accurate, the only thing that truely unites Baptists is their unwavering commitment to Believers' Baptism.
Believer's Baptism is one of the two ordinances
Yes, but a lot of churches has Two Ordinances, but the how and why is what sets the Baptists apart from them. Believers' Baptism is universal among Baptists because it is the only mode of baptism consistent with Justification by Faith. Baptists may vary in doctrine and between Conservative and Liberal or even Church Polity, but they do not differ over Believers' Baptism.
For those who have faith, no explanation is neccessary. For those who have no faith, no explanation is possible.
St. Thomas Aquinas
If one turns his ear from hearing the Law, even his prayer is an abomination. Proverbs 28:9
