>> Can you name a single doctrine that all Protestants hold in common? <<

All those regarded as “Protestant” by Catholics are not Christians. What’s you point? All Christians hold “believe on the Lord Jesus Christ and you will be saved – and your house” as doctrine. All Christians hold the following of Paul’s words to be doctrine.

"Most assuredly, I say to you, he who hears My word and believes in Him who sent Me has everlasting life, and shall not come into judgment, but has passed from death into life." (John 5:24)

Hebrews 10:10 By the which will we are sanctified through the offering of the body of Jesus Christ once for all. 11 And every priest standeth daily ministering and offering oftentimes the same sacrifices, which can never take away sins: 12 But this man, after he had offered one sacrifice for sins for ever, sat down on the right hand of God; 13 From henceforth expecting till his enemies be made his footstool. 14 For by one offering he hath perfected for ever them that are sanctified. 1 Corinthians 6:11 And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.

Hebrews 10:14 For by one offering he hath perfected for ever them that are sanctified.

The means by which we are saved is an unwavering faith in Jesus.

John 6:38-40 Jesus said, “I have come down from heaven not to do my will but to do the will of him who sent me. And this is the will of him who sent me, that I shall lose none of all that he has given me, but raise them up at the last day. For my Father’s will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise him up at the last day”

Rom. 3:28-30, "For we maintain that a man is justified by faith apart from works of the Law. 29 Or is God the God of Jews only? Is He not the God of Gentiles also? Yes, of Gentiles also, 30 since indeed God who will justify the circumcised by faith and the uncircumcised through faith is one."

Rom. 4:5, "But to the one who does not work, but believes in Him who justifies the ungodly, his faith is reckoned as righteousness,"

Rom. 5:1, "therefore having been justified by faith, we have peace with God through our Lord Jesus Christ,"

There is more but that should answer your question.
