Thomas Acquinas (they call him a "Saint") was known to have said, "Preach the gospel at all times and in all places ... use words if necessary."
are you kidding me?
THE GOSPEL IS WORDS. PERIOD.
Paul (they call him a "Saint" too) once said, "Faith comes by hearing and hearing by the Words of Christ." There is no gospel that is preached without words. The gospel will forever be the power of God unto salvation for all who believe, conveyed in the foolishness of preaching WORDS. You cannot believe propositional truths that are not ultimately conveyed using words.
Don't confuse good works and kind acts as synonymous with the Gospel.
