1 Corinthians 1:5

“That in everything ye are enriched by him, etc.] This is still a continuation of the thanksgiving for this church, that they were “enriched”, or plentifully and abundantly provided for by Christ, with all grace, with all the riches of grace; with his own unsearchable riches, of which they were made partakers, and the riches of glory, to which they were entitled by him; and all which come to them through his poverty, which makes his grace in the donation of these riches the more illustrious: and particularly the apostle is thankful, that they were enriched by Christ in all utterance, and in all knowledge; that not only they had the knowledge of the truths and doctrines of the Gospel,…”

“utterance--ALFORD from MENOCHIUS translates, "doctrine." Ye are rich in preachers or the preaching of the word, and rich in knowledge or apprehension of it: literally "(the) word (preached)." English Version (as in Co2 8:7) is better: for Paul, purposing presently to dwell on the abuse of the two gifts on which the Corinthians most prided themselves, utterance (speech) and knowledge (Co1 1:20; Co1 3:18; Co1 4:19; 1Co. 13:1-14:40), previously gains their goodwill by congratulating them on having those gifts.”

“That in every thing - In every respect, or in regard to all the favors conferred on any of his people. You have been distinguished by him in all those respects in which he blesses his own children. Ye are enriched by him; - compare the note at Romans 2:4. The meaning of this expression is, “you abound in these things; they are conferred abundantly upon you.” By the use of this word, the apostle intends doubtless to denote “the fact” that these blessings had been conferred on them abundantly; and also that this was a “valuable endowment,” so as to be properly called “a treasure.” The mercies of God are not only conferred abundantly on his people, but they are a bestowment of inestimable…”

“In all utterance and knowledge - Of divine things. These gifts the Corinthians particularly admired. Therefore this congratulation naturally tended to soften their spirits, and I make way for the reproofs which follow. 1 Corinthians 1:6”

“1:5 God had enriched the Corinthian church spiritually, specifically in eloquent words and knowledge. This probably refers to the spiritual messages and understanding (see 1:7) on which the church prided itself. Word and knowledge occur frequently in this letter: Paul acknowledges the abundant spiritual gifts that God has given the church in Corinth. Later, he corrects their distorted perspectives on these gifts (see 1:18–2:5; 3:18-20; 12:1–14:40).”
