In 1644, Wood was elected Professor of Divinity in Marischal College and minister of Greyfriars, Aberdeen, but not settled.
His appointment to this office by the university was owing to Cromwell's government, which, by the advice of James, afterwards Archbishop Sharp, wrote a letter to the ministers of St Andrews, and the masters of the university, requiring them to admit Wood as Principal of the Old College without delay.
On the establishment of Prelacy after the restoration of Charles II., Sharp did all he could to induce Wood to conform; and finding his efforts utterly ineffectual, he soon effected his removal from St Andrews.
By his instigation Wood was summoned before the Privy Council in July 1663;[12][2][13][6] and appearing, his place was declared vacant, while he was ordered to confine himself within the city of Edinburgh.
Wood, deeply grieved on hearing this report, dictated and subscribed a solemn testimony, before two witnesses and a notary, in which he declares it as his dying conviction, that Presbyterian government was the ordinance of God, appointed by Jesus Christ for governing and ordering his visible Church.
[3] He married: He is said to have left some very valuable manuscripts, particularly a complete refutation of the Arminian scheme of doctrine.
