When you sin
Against your brothers,
You are wounding
When it is weak.
οὕτως δὲ ἁμαρτάνοντες εἰς τοὺς ἀδελφοὺς καὶ τύπτοντες αὐτῶν τὴν συνείδησιν ἀσθενοῦσαν εἰς Χριστὸν ἁμαρτάνετε.
Paul said that when they were sinning (οὕτως δὲ ἁμαρτάνοντες) against their brothers (εἰς τοὺς ἀδελφοὺς) and wounding (καὶ τύπτοντες) their conscience (αὐτῶν τὴν συνείδησιν) when it is weak. They were sinning (ἁμαρτάνετε) against Christ (εἰς Χριστὸν). Paul told the Corinthians that when they sinned against their brothers, they were wounding their weak conscience. If they were sinning against their brothers, they were also sinning against Jesus Christ. To sin against a Christian brother is to sin against Jesus. They just had to be more careful in how they conducted themselves as regards those pagan idol worship foods. Are you careful in your everyday life?
