A.T. Robertson Commentary Romans 14:1

"But him that is weak in faith receive ye, [yet] not for decision of scruples." — Romans 14:1 (ASV)

Him that is weak (τον ασθενουντα). See on 1 Corinthians 8:7–12; 9:22; Romans 4:19.

Receive ye (προσλαμβανεσθε). Present middle imperative (indirect), "take to yourselves."

Yet not to doubtful disputations (μη εις διακρισεις διαλογισμων). "Not for decisions of opinions." Note δια (between, two or δυο) in both words. Discriminations between doubts or hesitations. For διακρισις, see 1 Corinthians 12:10; Hebrews 5:14 (only N.T. examples). For διαλογισμος see Lu 2:35; 24:38; Php 2:14. The "strong" brother is not called upon to settle all the scruples of the "weak" brother. But each takes it on himself to do it.
