Remove array elements that are present in another array

There is a list of words and list of banned words. I want to go through the word list and redact all the banned words. This is what I ended up doing (notice the catched boolean):

puts "Give input text:"
text = gets.chomp
puts "Give redacted word:"
redacted = gets.chomp

words = text.split(" ")
redacted = redacted.split(" ")
catched = false

words.each do |word|
  redacted.each do |redacted_word|
    if word == redacted_word
        catched = true
        print "REDACTED "
        break
    end
  end
    if catched == true
        catched = false
    else
        print word + " "
    end
end

Is there any proper/efficient way?
