C. Scotus’ own Opinion

77. I say therefore that the sort of simultaneity required is the sort that is required in human acts; for Christ refused to bind us to so subtle a simultaneity that scarcely could a man perceive or keep it.

78. Now simultaneity between a man’s deed and his word is when one of them begins before the other has totally finished, and this indifferently, whether the one will have finished before the other or the reverse. For example: if someone say this sentence ‘do this’ and he stroke his beard at the same time, whether he begin his act [of stroking] before the speaking of the words or vice versa (provided however that one of them not be finished before the beginning of the other), it will be said ‘he said this and did this at the same time’.

79. Thus I say that whether the priest immerse first with one immersion (where it belongs to the custom of the country to immerse more than once), and afterwards with a second immersion begin the words, or whether he begin the words and at the saying ‘I baptize you’ he immerse along with the words that follow, the simultaneity is sufficient -provided, in brief, the speaking not finish before the beginning of the washing, nor the washing finish before the beginning of the speaking.
