My words will be in regular font.
he’s repeatedly used words that lend one to think he believes in impanation or consubstantiation..
Only if you presume what he is saying must be unorthodox because he does not use specific words you want him to use or because your judgment is formed by an presuppositional inclination against him. St. Francis de Sales counseled against "people whose judgment is solely formed by inclination; who always think well of those they like, and ill of those they dislike." This principle applies to the words and actions of others. As Fr. Quadrupani noted in an eighteenth century spiritual instruction to devout souls referencing St Francis de Sales:
"Always be ready and willing to excuse the faults of your neighbour and never put an unfavourable interpretation upon his actions. The same action, says St. Francis de Sales, may be looked upon under many different aspects: a charitable person will ever suppose the best, an uncharitable one will just as certainly choose the worst."This principle also made it into the CCC in the section on the eighth commandment and violations thereof (CCC 2478).
can you find similar words before 1965?
It would not matter if I could or could not. But if you want words "prior to 1965" for some arbitrary reason, the words of Quadrupani are from 1795 and the words of de Sales are from 1619.
