Well, hmm (furrowed brow) right: I thought he'd been convicted by an Anglican court first (Cuthbert Tunstall?), and then by a Catholic court in what is now Belgium. (Take off 5 points for that.)
You're entirely correct that Tyndale supported in effect the Catholic position against Henry VIII's divorce; that incurred the king's wrath and set in motion the "politics" of his betrayal and eventual execution.
The cruelty of that period is hair-raising. I recently read Ackroyd's bio of Thomas More: I have to think he repented his part in the blood-spilling, before his own was spilt.
"Scripture derives its authority from Him who sent it. Would you know the reason why men believe in Scripture? It is Scripture. — It is itself the instrument which outwardly leads men to believe, whilst inwardly, the spirit of God Himself, speaking through Scripture, gives faith to His children." "The man who throws off the worldly existence which he has lived far from God, and receives by a living faith the complete remission of his sins, which the death of Christ has purchased for him, is introduced by a glorious adoption into the very family of God.""The authority of Jesus Christ is independent of the authority of the Church...Holy Scripture is the first of the Apostles, and the ruler in the kingdom of Chrst."
Sola fide.
First: He maintains that faith alone justifies.
Second: He maintains that to believe in the forgiveness of sins and to embrace the mercy offered in the Gospel, is enough for salvation.
Third: He avers that human traditions cannot bind the conscience, except where their neglect might occasion scandal.
Fourth: He denies the freedom of the will.
Fifth: He denies that there is any purgatory.
Sixth: He affirms that neither the Virgin nor the Saints pray for us in their own person.
Seventh: He asserts that neither the Virgin nor the Saints should be invoked by us.
