It is important that any quotes you post be in context. The above response from Adams and Hancock was a response to a threat from the king of England. Here is what Adams said about our Constitution, in context:
The United States of America have exhibited, perhaps, the first example of governments erected on the simple principles of nature; and if men are now sufficiently enlightened to disabuse themselves of artifice, imposture, hypocrisy, and superstition, they will consider this event as an era in their history. Although the detail of the formation of the American governments is at present little known or regarded either in Europe or in America, it may hereafter become an object of curiosity. It will never be pretended that any persons employed in that service had interviews with the gods, or were in any degree under the influence of Heaven, more than those at work upon ships or houses, or laboring in merchandise or agriculture; it will forever be acknowledged that these governments were contrived merely by the use of reason and the senses....
Unembarrassed by attachments to noble families, hereditary lines and successions, or any considerations of royal blood, even the pious mystery of holy oil had no more influence than that other of holy water: the people universally were too enlightened to be imposed on by artifice; and their leaders, or more properly followers, were men of too much honour to attempt it. Thirteen governments thus founded on the natural authority of the people alone, without a pretence of miracle or mystery, which are destined to spread over the northern part of that whole quarter of the globe, are a great point gained in favour of the rights of mankind.
-- President John Adams: "A Defense of the Constitutions of Government of the United States of America" (1787-88)
The Founders were indeed wise to construct a secular Constitution and system of government that would not be vulnerable to dictates of popes, kings, or charismatic religious leaders. But to say that this is 'in context' and thus no religious morality is written into it would be a misnomer. For John Adams also said:
"It is religion and morality alone which can establish the principles upon which freedom can securely stand. The only foundation of a free constitution is pure virtue."

"[W]e have no government armed with power capable of contending with human passions unbridled by morality and religion. . . . Our constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other."
(Source: John Adams, The Works of John Adams, Second President of the United States, Charles Francis Adams, editor (Boston: Little, Brown, and Co. 1854), Vol. IX, p. 229, October 11, 1798.)
"The moment the idea is admitted into society, that property is not as sacred as the laws of God, and that there is not a force of law and public justice to protect it, anarchy and tyranny commence. If "Thou shalt not covet," and "Thou shalt not steal," were not commandments of Heaven, they must be made inviolable precepts in every society, before it can be civilized or made free."
