John Wycliffe said this quote

The true Christian was intended by Christ to prove all things by the Word of God: all churches, all ministers, all teaching, all preaching, all doctrines, all sermons, all writings, all opinions, all practices. These are his marching orders. Prove all by the Word of God; measure all by the measure of the Bible; compare all with the standard of the Bible; weigh all in the balances of the Bible; examine all by the light of the Bible; test all in the crucible of the Bible. That which cannot abide the fire of the Bible, reject, refuse, repudiate, and cast away. This is the flag which he nailed to the mast. May it never be lowered!

~ John Wycliffe

Visit those who are sick, or who are in trouble, especially those whom God has made needy by age, or by other sickness, as the feeble, the blind, and the lame who are in poverty. These you shall relieve with your goods after your power and after their need, for thus biddeth the Gospel.

~ John Wycliffe

In order to the existence of such a ministry in the Church, there is requisite an authority received from God, and consequently power and knowledge imparted from God for the exercise of such ministry; and where a man possesses these, although the bishop has not laid hands upon him according to his traditions, God has Himself appointed him.

~ John Wycliffe

It is certain that the truth of the Christian faith becomes more evident the more the faith itself is known. Therefore, the doctrine should not only be in Latin but also in the common tongue, and as the faith of the Church is contained in the Scriptures, the more these are known in the true sense, the better.
