Whilst the duration of his early years of ministry reflected the slightly less difficult times for Catholics during that period, the Gunpowder Plot changed the atmosphere making it far more hostile.
In 1635 he was one of a number of priests who would pay a bond and then be released from prison, which allowed him to minister to the local Catholic population in London on a regular basis.
With the King having to flee London in early January 1642 following his failure to capture the leaders of the Parliamentary actions against him, the capital was left in control of the Parliamentarians.
Now eighty years of age, by nature a slightly timid person and being somewhat infirm, Reynolds admitted his fears of facing execution and how he would be able to manage the ordeal he was soon to undergo.
He pointed out that in forty years work as a priest in England, no one could testify to him having ever uttered a word of treason and that his sole aim had been to ‘reduce strayed souls to the fold of the Catholic Church’.
Turning to the sheriff overseeing the execution, he specifically thanked him and for his patience whilst he addressed the crowd and prayed that God would reward him for that by one day making him a saint in heaven.
Thomas Reynolds was beatified by Pope Pius XI on 15 December 1929,[12][13] therefore he is among the group of One Hundred and Seven Martyrs of England and Wales.
