What do our biases bring to the table? Mostly presuppositions, the act of presupposing; a supposition made prior to having knowledge (as for the purpose of argument). We all have them. So do our denominations and churches. A supposition can be defined as a message expressing an opinion based on incomplete evidence, a hypothesis that is taken for granted, or a cognitive process of supposing. Other synonyms include assumptions, conjecture, guess, hypothesis, speculation, and surmise. A presupposition is therefore the making and accepting judgments decisions prior to having “good” evidence.
The most frequent evidence presented in a biblical discourse are “proof texts”. Using a proof text to establish a doctrinal or theological position is quite different than providing the same text as the “foundational text” to identify/discover a biblical doctrinal or theological position. A foundational text is the text that is used in conjunction (built upon) with other texts relating to the same subject matter, even those texts that seem to disagree with the argument being presented.
For example: What must one do to be saved? Well, here we go –
Acts 2:21 And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.
Acts 2:36-38 Therefore let all the house of Israel know assuredly, that God hath made that same Jesus, whom ye have crucified, both Lord and Christ. Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do? Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. [Salvation implied]
Acts 16:30-31 And brought them out, and said, Sirs, what must I do to be saved? And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.
Also of note are Mark 16:16, Luke 7:5, 18:42, Romans 8:24, 10:9-11, 10:13, Eph 8:26, 1Tim 2:15, & Titus 3:5,
There seems some disagreement among the authors as what a person must do to secure their salvation. Any of the above can be used as a “proof text”, and likewise, may be used as a foundational text upon which the doctrine may be developed. Most often proof texts are cited as the single text in a discourse – very poor choice of supporting an argument when there are competing texts, as included text in the above list.
Yet there is another problem associated in developing a doctrine, knowing what the words and/or phrases cited in a text mean, especially in the first century language and culture. As an example, what did “call on the name of the Lord” mean? What did it in tale? What did “believe on the Lord” mean? What did that require? What is the context of each scripture cited? If they support one another – how? If not, can the texts be reconciled?
My recommendation: Avoid the practice of poof texting.
