He was an Anglican that wanted to understand the origins of Catholic doctrines concerning Mary (which he did not agree with at first). After his study he eventually joined the Catholic Church.
Too bad his "study" wasn't the study of 2 Tim. 2:15. "STUDY to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth." Of course he ended up joining the Catholic Church. That is where all who ignore/refuse to study God's word, rightly divided, end up. That, and connecting imaginary dots to IMPLICIT poofs of Scripture, buried so deep between the lines you could strike oil before you strike a meaning you like.
Veneration is not worship.
2 Tim. 2:15 confirms scripture is inspired and without error. No doctrine should ever contradict scripture. Agreed. Nothing the Catholic church teaches contradicts scripture.
